I've got a HP TX2 convertible tablet on win7. I loved taking notes on powerpoint slides for my teacher that provided them via vspace. My problem was that battery life on the TX2 was a bit shy of a class period at times. The newer TM2 gets about 5 hours, so that would be better.
I love the look of the HP slate for this kind of thing.
A power efficient SSD would help a lot, since they resume from hibernate and sleep so fast.
