The only usable item these days (and it would only be half-functional as their app stores or such have long been discontinued) would be the later Windows Mobile 7 devices, or Windows Mobile 6. Nokia had a really nice BlackBerry clone that ran 6, had a keyboard and all. i remember drooling over one of those if i saw it back before the iPhone had even been released. it was the era of the Moto RAZR (the original flip phone) and Symbian devices. However, today, i would find it hard to have. it's like a Zune HD. sure, the device isn't THAT old, but it's old enough...Heck, i still have my old BlackBerry Curve. App World only half-works on it if i reactivate the old Virgin Mobile account, but the apps currently installed--Google Voice, Gmail, Weather Channel and Pandora--are no longer available, so if i deleted them, i couldn't get them back. that's how far gone that device has become.
