While not strictly PDA - I think the subject matter is still perfectly relevant to this list. Laptops need mobile connectivity too.
My experience(s) don't relate to a single device, but I would advise you against going that route in any case - more on that later. I've used gprs over bluetooth with my cellphone. It worked just fine, although it was nothing like broadband speeds - which I have apparently become quite accustomed to. Configuring bluetooth under linux is a little tricky (or was at the time) just because getting BlueZ or Affix to work well is a little confusing - a few levels you have to initiate manually before bringing the (in my case) ppp up. I'll be happy to help you diagnose anything if I can remember how :) As far as integrated device - I would advise against this because they traditionally aren't as powerful as their separate counterparts. Take the nokia n-gage (which a newer model was just announced for) - cellphone and game system... in most opinions doesn't do either signifigantly well. Another device is the Danger Sidekick (Tmobile hiptop [I might have those reversed]). This I have to admit is a very slick device - and you get better performance since everything is proxied and their servers do a good job of stripping out the useless bits - but you're limited with the usability. You can't use the device as a modem like a normal cellphone - if, for example, you had your laptop handy and wanted to get online with it. You can't use the device without a proxy - and the SDK (I believe it was finally released) isn't much good because you can't get the program on the phone without a bunch of hoops. irda works fine as well, but it's a pain lining things up - bluetooth is nice because it's low power (unlike 802.11b) and works well once devices are paired. Speaking of power - if you just want to talk to someone on the phone you're burning your PDAs battery - and if you just want to use your PDA you're burning your phones battery... nor can you just take one with you somewhere... I've got a bluetooth cf card on order from amazon (ambicom) that I'll be trying out the pda game with. I'll let you know how well it works if you're interested.
