You’ll never all the uses you’ll have for it until you’ve learned to live with it. I’ve perpetually had one in my pocket for more than five years, including the 15 months I’ve lived in Iraq. Right now I’m carrying a Toshiba e830. I upgraded from an e755 but I don’t especially recommend the Toshibas; I just happen to have worked for them once upon a time.
Mine daily syncs all the information in my MS Outlook in my home PC with the one at work, and verse-visa. I know anything I create in my PPC’s notes automatically will be backed up to both my work PC and my home PC the next time I sync. And, as previously mentioned, it’s a great DayTimer and mini word processor.
Mine connects to AvantGo every time I make an ActiveSync connection and downloads that day’s online Reader’s Digest version of the Christian Science Monitor, NY Times, Dave’s iPaq, Reuters & BBC Sports, Sydney Morning Herald, Wired & Yahoo News and a bunch of others. It’s my way of keeping up with what’s going on in the world when there’s a lull in the chaos.
And there’s a slew of killer PPC games if I feel the need to kill some Nazi occult researchers, along with some time.
I have Microsloth Money on mine and use it in lieu of a check register (it also maintains my balance for me).
I keep electronic copies of all my ID documents (passport, driver’s license, handgun permit, social security card, government ID, Blue Cross card and anything else I can think of) in PDF format.
Another app stores all my credit card information and all internet account logons in encrypted files.
I have an IP address scheme calculator on mine to figure subnetting for me at work. In jobs where wireless networking was permitted, I’ve connected to servers remotely from my PDA via another freeware, VNC, and actually got something accomplished during those completely irrelevant staff meetings. Or surfed the web and no one could tell I wasn’t merely taking notes. ;-)
I use a video shrinking app to reduce DVD movies to a size that will fit on an SD or CF card, usually carrying 4 movies on a single 1GB card. It’s low resolution but looks okay on the small screen. Beats the heck out of watching Emirates Air’s lame-o in-flight movies. It also doubles as a respectable MP3 player, holding 10-12 CDs per flash card.
I have a freeware that transforms my IR transmitter into a universal remote control. I’ve yet to find a TV in a waiting room that I couldn’t change the channels on at will.
I can pull my PDA out of my pocket and tell in 30 seconds whether there’s available WiFi signal, without having to fish out my laptop. Along with my BT cell phone, I can surf and do E-mail anywhere there’s GPRS signal (which is just about anywhere there’s cell phone signal).
Among the more esoteric functions, I found a freeware app to guide me through the Paris Metro. You input your start and destination points, tell it whether you want the fastest route, the one passing through the fewest stations, or the one with the fewest changes of line, and it gives complete details, right down to station numbers, platform numbers, direction of travel and estimated time en route.
I can get into a cab in Dubai and show the Jordanian driver the screen on my PDA, which is displaying the address of where I want to go in Arabic. And a graphic world clock tells me at a glance whether it’s daylight in Tennessee and, consequently, whether I’m about to telephone my daughter before she’s had her morning coffee.
This summer I’m going to Italy and I plan to buy a GPS CF card to fit in mine to turn it into a GPS that hopefully will keep me from once again getting repeatedly and hopelessly lost in all those medieval mazes of inner city streets. I also will load an English-Italian dictionary with audible pronunciation guide.
Most of the horror stories about network connectivity problems are leftovers from the early days; they’ve become markedly easier to network in the last couple of years. I have Skype on mine and can use it for an IP phone anywhere I can make a WiFi, BT or IR connection to the Internet. Two cents a minute from anywhere in the world to anywhere in the world. And, since it contains all the contacts from both my PCs at work and at home, I never have to worry about forgetting an important telephone number or address.
It’s not just commercial companies, common folk also are continually creating more (freeware) apps for the devices too, and, like crackers, they do it for bragging rights, not for profit. There’s virtually nothing you can do with a laptop that can’t be done on a PDA. How much use you find for it will vary directly with how much interest you take and how much effort you invest in making it pertinent. I’ve made mine an integral part of my life. The people who tell you a PDA is worthless are the same recycled Luddites who told you 20 years ago that you'd never have use for a computer in your home.
Downside? If you can’t get it on a charger in time and the battery completely discharges, you’ll lose all your installed apps and most of your stored information (you did back up with your laptop last night, didn’t you?).
