Considering I need:
1)A long lasting battery life to play Mp3s
2)The best screen to watch my photos
3)Decent video playback
4)Dual slot expansion
6)Bluetooth GPS ability
PS:I'm not an hardcore gamer (u could ask me: what the hell are u doing here so??
1 - the Loox 720 has much, much better battery life than the Asus a730. It also has a battery charger on the cradle making it much easier to keep a second battery charged. Also - Mugen are shortly coming out with an extended battery for the Loox 720.
2 - Opinions differ but I would say the Loox 720 is the best screen I've seen to date (and boy have I seen them all!).
3 - BetaPlayer works like a charm on the 720 and its creator - Picard - has done a lot to improve it further.
4 - Dual slot - check...
5 - Bluetooth - the Loox 720 has version 1.2 which means less interference with WiFi than version 1.1 (which is what the Asus has).
6 - Bluetooth GPS - well, I use a BT GPS solution almost daily with my Loox 720...
To correct you on one point, however - the Loox 720 deosn't have rubber sides (bearing in mind what a nuisance they were on the iPAQ 221x that is not a bad thing...)
