Buying a PDA

Tip! You need accessories. These are the basic, non essential goodies that are accompanying your PDA, like a nice leather case, a spare battery, a data/recharge cable, a recharge cradle and the like.

Buying a PDA is not an easy decision. There are so many things to consider and so much research to do to get your dollars worth. You have to ask the questions. How much do I want to spend? What do I want my PDA to do?

Before deciding on a PDA you should know exactly what feature it has and if it meets your particular needs. PDA stands for personal digital assistant and it should perform exactly that task. It should help in making your life more organized and easier.

A new PDA does not need to be upgraded annually, so it is a worthwhile investment. It can perform several functions, some of which include address book, notes taker, GPS navigator, calculator and much more.

Tip! Start with a research first. Always look for a few Internet forums about your PDA and ask around about the item you want to get.

Given that you are ready to go forward with the purchase, your choice of a PDA model will depend on your requirements?what you want it to do. A few things to take into consideration would be the amount of memory the PDA has. If you want to store large documents or multimedia on it then you will need something with a large/expandable memory. The second is the size of the PDA. If you don’t like lugging around heavy things then get something lighter that will better suit you. The third is the battery life of the PDA. If you want to use it heavily and still be able to turn it on then you’ll need something with an extended memory life.

Tip! Make sure what brand of PDA you want. If you already own a PDA - that is easy.

A PDA can be bought almost anywhere. You can buy one online from just about anywhere or, you could buy one from a physical store. I would recommend buying one from a physical store as this will allow you to evaluate both size and weight to determine whether the PDA will suit your needs.

Lose a Laptop or PDA? You Get Your Stuff Back with Property ID Asset Tags

Tip! Your own PDA in now being repaired. This is obvious - your PDA is broken or malfunctions and it’s being repaired.

You’ve finally done it, you left your laptop at the coffee shop, your cell phone at the supermarket or your PDA on the counter at the office supply store. Maybe you forgot to pick up your iPod from the ATM, where you put it down to answer your cell phone during a banking transaction. Several new companies have launched with the express purpose of helping us all find stuff we inevitably lose every day. Each are using the power of the web, plus toll free phone numbers and a database of unique ID numbers assigned to each item and registered to owners - on special “asset tags” or “property ID tags”.

1,200 cell phones, 1,500 sets of keys and over 300 PDAs and laptops are turned into the Las Vegas International lost and found department annually. - McCarran Int’l Airport Security, July 2003

140,000 items are found annually on Southwest Airlines flights, 50,000 items at Enterprise Rent-A-Car, and 20 a day at some Avis Rent-A-Car locations. Despite best efforts, fewer than 1% are returned. - The Wall Street Journal, November 2003

Several companies have launched to help return lost property represented by web sites www.StuffBak.com, www.TrackitBack.com www.Boomerangit.com, each company offering to help you recover lost valuables.

Tip! If you are surfing the web, there are types of viruses and Trojan horses who ‘know’ how to penetrate your PDA and do their worst. You therefore need proper protection from infected files, just like any PC user who surfs the web, downloads files, reads emails etc.

An Irish startup has launched based on that same concept of marking expensive portable electronics, laptops, PDA’s, cell phones, MP3 players and other valuables with their asset tags (labels with unique ID numbers). That firm also has a website and toll free phone lines where items can be reported found. The Irish company is named www.yougetitback.com and has a cute, black and white spotted puppy dog as a mascot. The concept of the dog “fetching” lost items and returning them to you is easy to understand. The company tag line is “The Lost And Found Company” for obvious reasons.

Tip! Make sure what brand of PDA you want. If you already own a PDA - that is easy.

What is not so obvious to most is the idea that many people are honest enough that they would actually turn in a lost valuable. Most of us assume that if we leave a laptop or an iPod on the bus or subway, that we’d never see them again. But the companies cite several experiments done in the US by 8 local television news stations and one by a USA Today columnist, Edward Baig, to prove that if those valuables are labeled with special “asset tags”, that people will, more times than not, call the toll free telephone numbers printed on the tags and return the expensive items.

Tip! Full Internet and email capability. This is a standard feature among PDA’s today, but it’s worth mentioning.

www.usatoday.com/tech/columnist/edwardbaig/2004-06-09-baig_x.htm

The television stations had a 75% success rate in getting their “lost” items reported and turned in, while columnist Baig got back 4 of 6 purposely “lost” items (two thirds) in his experiment. Baig mentioned in his column that it was the least expensive things that were never reported or returned - a CD case full of music and a calculator.

If this trend takes hold and becomes popular in the consumer market, it will mirror a concept long used by corporate, government and military organizations. Those large companies, educational institutions, governments and the department of defense have long put asset tags on property over a specified dollar value.

You can see “fixed asset tags” on items ranging from street light poles to heavy machinery. Those items have long been tagged and labeled with unique ID numbers and bar codes printed onto them to facilitate electronic scanning.

More recently, corporate and government entities have begun placing asset tags on more high value movable items like laptops, PDA’s, scanners and cell phones carried by employees in their work. This facilitates the identification and return of those “movable assets” when they are lost on the job by careless or distracted workers.

Tip! Do your won research and make up your mind as to the PDA model you want to get. DO this research before you go shopping, so you’ll have a good background about which model you want, and what are the potential problems it has.

The launch of companies like StuffBak, TrackitBack, Boomerangit show that valuable electronic, digital items are being lost far more often by consumers and they are seeking ways to get their goodies back when they misplace them. Asset tags for the masses may become popular enough to support consumer oriented companies to label consumer items.

StuffBak has partnered with retailers like CompUSA and Sears, while BoomerangIt works product tie-ins with Pioneer, Toshiba, Palm and Seiko Instruments, along with nearly a dozen bicycle manufacturers - (due to their roots as a bicycle recovery company). BoomerangIt is also working with the www.ncpc.org/ National Crime Prevention Council (Think McGruff the crime fighting dog and “Take a bite out of crime”). They also work with local police departments in return of stolen goods with the tags. TrackitBack has partnered with Staples and BestBuy stores - so all are agressively marketing their offerings in the consumer marketplace.

Tip! Understand that the items on ebay may not be presented as they really are. You don’t see the PDA with your own eyes.

Each offer business incentives for larger sales of ID tags exceeding 50 or more, with invitations to companies to contact them for volume pricing.

The movement of asset tags into the consumer marketplace is an unexpected development that may be logically extended into property insurance discounts and other unexpected areas. Asset tags are turning up on consumer goods through national retailers and product bundling with cooperating “lost and found” companies to bring your laptop, PDA or iPod back home when it is lost.

PDA Battery Degradation and Power Loss

Tip! Do your won research and make up your mind as to the PDA model you want to get. DO this research before you go shopping, so you’ll have a good background about which model you want, and what are the potential problems it has.

Extending your PDA Battery Life so that you get the most cost effective use of your PDA battery begins with always keeping a spare pda battery replacement. PDA batteries are cheap enough that owning a backup pda battery makes absolute sense.

Beyond a spare pda battery replacement you can use some basic battery conditioning techniques to help further extend the life of your pda battery like: use the AC adapter or pda cradle at a desk, powering your pda battery down when not in use, dimming your pda screen down, and using peripherals wisely.

Tip! Full Internet and email capability. This is a standard feature among PDA’s today, but it’s worth mentioning.

But with PDA batteries there is far more going on internally that work against the life of a pda battery. Contained within your PDA Battery is a design and chemistry make-up that impacts your battery life far more than your usage activity and there is no amount of conditioning you can do to preven the ultimate power loss of your pda battery.

For example we know that batteries are rated by their voltage, their mAh, and of course the chemicals contained within. These three technical facts about your battery give some insight into the actual life of (energy stored within) your battery.

Tip! Your own PDA in now being repaired. This is obvious - your PDA is broken or malfunctions and it’s being repaired.

But the length of time a pda battery can operate is not linear to the amount of energy stored in the battery. In fact their are four ongoing problems with all batteries that affect performance and the extended battery life of your pda.

They are: declining capacity, increasing internal resistance, elevated self-discharge, and premature voltage cut-off on discharge.

These are more complex issues that are beyond user control and are wholly contained within your pda battery and within your device! As we will see these issues (declining capacity, increasing internal resistance, elevated self-discharge, and premature voltage cut-off on discharge) do more to cause PDA Battery Degradation and PDA Power Loss than your typical PDA owner could ever do.

Tip! The H6315 is an integrated PDA + cell phone. In the US, this device works perfectly along with the T-Mobile and Cingular networks.

Declining Capacity

Declining capacity is when the amount of charge a battery can hold gradually decreases due to usage, aging, and with some chemistry, lack of maintenance. PDA batteries are specified to deliver about 100 percent capacity when new but after usage and aging and lack of conditioning a pda battery’s capacity will drop. This is normal. If you are using a pda battery (or any lithium-ion or lithium-polymer battery) when your battery’s capacity reaches 60% to 70% the pda battery will need to be replaced. Standard industry practice will warranty a battery above 80%. Below 80% typically means you have used the practical life of a battery. Thus the threshold by which a battery can be returned under warranty is typically 80%.

Tip! Make sure what brand of PDA you want. If you already own a PDA - that is easy.

Loss of Charge Acceptance

The loss of charge acceptance of the Li?ion/polymer batteries is due to cell oxidation. Cell oxidation is when the cells of the battery lose their electrons. This is a normal process of the battery charge creation process. In fact every time you use your pda battery a loss of charge acceptance occurs (the charge loss allows your battery to power your pda). Capacity loss is permanent. Li?ion/polymer batteries cannot be restored with cycling or any other external means. The capacity loss is permanent because the metals used in the cells run for a specific time only and are being consumed during their service life.

Internal Resistance

Internal resistance, known as impedance, determines the performance and runtime of a battery. It is a measure of opposition to a sinusoidal electric current. A high internal resistance curtails the flow of energy from the battery to a pda device. The aging of the battery cells contributes, primarily, to the increase in resistance, not usage. Expect a typical life span of a Li?ion battery to be one to three years, whether it is used or not. The internal resistance of the Li?ion batteries cannot be improved with cycling (recharging). Cell oxidation, which causes high resistance, is non-reversible and is the ultimate cause of battery failure (energy may still be present in the battery, but it can no longer be delivered due to poor conductivity).

Tip! If you are surfing the web, there are types of viruses and Trojan horses who ‘know’ how to penetrate your PDA and do their worst. You therefore need proper protection from infected files, just like any PC user who surfs the web, downloads files, reads emails etc.

Elevated Self-Discharge

All batteries have an inherent self-discharge. The self-discharge on nickel-based batteries is 10 to 15 percent of its capacity in the first 24 hours after charge, followed by 10 to 15 percent every month thereafter. Li?ion battery’s self-discharges about five percent in the first 24 hours and one to two percent thereafter. At higher temperatures, the self-discharge on all battery chemistries increases. The self-discharge of a battery increases with age and usage. Once a battery exhibits high self-discharge, little can be done to reverse the effect.

Premature Voltage Cut-Off

Some pdas do not fully utilize the low-end voltage spectrum of a pda battery. The pda device itself cuts off before the designated end-of-discharge voltage is reached and battery power remains unused. For example, a pda that is powered with a single-cell Li?ion battery and is designed to cut-off at 3.7V may actually cut-off at 3.3V. Obviously the full potential of the battery and the device is lost (not utilized). Why? It could be something with elevated internal resistance and are pda operations at warm ambient temperatures. PDAs that load the battery with current bursts are more receptive to premature voltage cut-off than analog equipment. High cut-off voltage is mostly equipment related, not battery.

Tip! You need accessories. These are the basic, non essential goodies that are accompanying your PDA, like a nice leather case, a spare battery, a data/recharge cable, a recharge cradle and the like.
