Tablet for School - the HP Slate

Ahhh there are so many tablets now its making my head spin. I can't wait to go home and play with them all at my nearest Fry's.

So far.. my pick is for the Ipad 2, for a lot of reasons. Mostly, battery life, and applications. 
... but watching this video made me realize I really really do think a pen can be super useful in the Lecture hall.... its making it very hard to resist the allure of something like the HP Slate 500 for next semester...
