It probably got the USB ports on the keyboard? Might be wrong here.

Anyways transformer will most probably be my first tablet. After the new update it seems to have gotten solid reviews, only 3.0 tablet with ISP screen, all the ports, battery life and surprisingly cheap compared to other high profile 3.0 tablets for what if offers.
Only other option is the newer version of tab 10.1 with memory card slot, but both transformer and 10.1 should arrive here somewhere around June so i'll wait till that to make my final decision.

Great 10 min video of the tablet
