does a very good job of how mobility is to really work as a tablet/laptop. You can peel away the keyboard, now you need an input device. No better solution than a finger, right Apple?
Attach the keyboard back again, now you can use the keyboard. I think the switch between is very practical for first revision and appeals to many. With the recent Windows 8 flop, that has really cast a dark cloud over the future of the OS.
What I like about the SP3 are the additions of USB, etc. Just a very good stab at the OS with 8.1 and multi-touch.
