New iPad - is it Fish or Fowl?

A recent article in the Fox News asked if the direction being taken by many of the newer eReader devices and the iPad in particular, is really a better eReader or a "lite" laptop or netbook. I am interested to see how my students (and the market) respond to this choice. Do we want - or need - a light workstation that's portable or just an eReader for student textbooks. Will the market for eTextbooks be closer to textbooks or will students want a multi-purpose device?   Comments?
