Ok, for taking notes you want a real keyboard on your thing, some good resolution, and it being 2, maybe 3 pounds.
Oh yeah, and 10 to 12 hours of battery when new so it drops to around 8 hours during the years you use it.

Do you need specific apps for your courses ? Because I'm checking the asus eee pad transformer and it looks good but it's running with Android.
