It's basically a mini-touchscree notebook as you called it. The major problem with devices like this is the OS used, Windows XP, is not finger-friendly. I've got my Viliv S5 which I mainliy bought for video playback and GPS, both of which it does really well. I hated converting my videos over to another format to play on the iPod or PSP so this was a welcome addition to my gadget family. The GPS on the S5 and X70 both work really well with GarminP MobilePC (although the software is a bit outdated, still able to use latest maps).I've wanted one of these for a while, but I don't know how useful they actually are and whether my iPod Touch can already do most of the things that one of these can. Do they act like a mini-touchscreen notebook?
