Looking at the asus transformer, I was thinking: - wouldn't it be nice if there's a standard for this sort of thing? so the 'transformer' part of ASUS can be interchangeably connected with other tablets (not just through a bluetooth connection, but also for power charging and even usb hub and memory card slots). then ... "wouldn't it be nice if they use magnetic mechanism like the iPad2 to hook the parts together? that would make the connection more robust and works with more formfactor/sizes... hmmm ..... is apple planning something up this alley by going all magnetic with iPad2?
