IDK, I don't see a purpose for people who already have an iphone and a laptop. It's neither. I don't want to have to carry all three around. It looks cool, with a fun interface, but basically is a huge iphone/ipod touch without the phone.
If all my mods were done to my Z and I had a lot of extra cash laying around, I might buy one just for couch surfing the net, otherwise I say make the iphone screen a 1/2 bigger give it G4 and a faster processor and call it a day.
