DR Danise - I went to CompUSA. There was a large kiosk display by the digital camera and PDA display cases.
As for software, most of it was games (solitaire variations, arcade stuff, etc.). But there were also Pocket PC versions of Money, Streets and Trips, calendar and scheduling programs, etc. I knew all that stuff was out there, I had just hadn't actively looked at any of it.
As for accessories - portable, folding keyboard (full-size keys!), battery pack attachments, other "packs" which allow you to use compact flash cards and PCMCIA cards (like the ones you would use for a laptop), etc.
As for a modem, most of the modem cards would require one of the add-on "packs" since they would require extra battery power to run. Wired (with a phone jack in them) and wireless modems are available. Surprisingly, most of the modems run between $60-80. However, the "packs" run about $150, so... I did see a listing for a wireless modem/network card that can plug right into the Pocket PC slot, but they didn't have one in stock.
When I got home, I started researching a bunch of stuff on the web. There is a LOT of stuff out there. There was one technical site which sort of helped, but it was a bit too technical (even for me, and I usually like all that specificity). But there are also a lots of vendors that sell software and hardware for PDAs/Pocket PCs. Just "google" your Pocket PC make and model number, and a bunch of listings will come up. -That's what I did.
In the meantime, here are a few of the sites that had some real cool stuff:
http://www.pocketgear.comhttp://www.mobileplanet.comhttp://www.pdastreet.comAnd the technical site I visited was:
http://www.cewindows.net*There is some very good information on the site, but, again, there is a lot of technical jargon to wade through depending upon what you are looking for.
Oh! I also got a nice listing from my manufacturer's website. I just plugged in the model number, and a whole listing of accessories came up - even stuff made by a third party. Of course, this was one of the last places I looked. DUH!
Hope this helps. Just e-mail me if you need any help - since I'm still investigating the possibilities too.
