Yeah, remember how little you can do at once. On a laptop you can have multiple windows open, sharing the screen. On this, you'll need to switch back and forth between windows, which could get pretty annoying for, say, research papers. I'm going from an iPad to the TF Prime (unless there's some big flaw with the Prime that makes itself known once it comes out), and part of the reason for that is that it'll be better for taking notes in class than trying to use my iPad, which I don't have a keyboard for and which has a hard time keeping up with my typing if im taking notes on a PowerPoint lecture. It'll be good to have on those days where I don't need my full computer and just want to carry a light load.
However, my computer still gets plenty of use, and if I had to keep only one, it would definitely be my laptop. In terms of downloading lectures, watching lecture captures, and ESPECIALLY in terms of taking notes while doing those things, laptop wins.
