I don't know about that, I think you should give the tablet mode a try before you speculate about what it can and can't do.

I use my SP2 a lot with the Pen and OneNote, which provides automatically digitized handwriting that is viewable and searchable from any computer. It's a pretty killer app but I would probably still be using pen and paper notebooks before someone integrated a screen and highly accurate pen in one device.

You may find some uses for the tablet that you never imagined before.
