Good review, but i too have played with the ipad, and for what it cost, it seems like the Shuttle is way better, and way cheaper. Not to mention the shuttle (being a simple intel board) is MUCH MUCH MUCH easier to "mod", "upgrade", and "trick out".
The only thing it seems to me that the ipad offers is a giant iPhone. and personally, other than the great accelerometer, and the easy "app" idea (which i'd like to see done in dotNet and not java, BLEH!), iPhones are pretty useless unless your just a mindless drone who doesn't care to really get creative or intuitive with there hardware.
