My feeling is that, if I could have an electronic version that you could mark up appropriately -- I would start to get the same feeling about the personalized electronic copy as well.

However, there is one huge problem with textbooks on things like an iPad, that I've already run into in other contexts, and it has nothing to do with feel, or annotation (which still sucks on an ipad): You can't have more than one book open at one time. Not multitasking in the ipad sense, but literally, two ipads. Can't do it unless you spend another $600.

My feeling is that these device are the future, but two(three) things need to happen -- you need to be able to write/draw on these just as well as you can on paper (or close to it). And they need to be dirt cheap enough that everyone has three of them handy (and can have them communicate seamlessly).
