Maybe I'm being a prude, or maybe it's just inertia, but does everyone have an easy time replacing a textbook with an electronic device? An argument can probably be made about how ever-advancing technology might make note-taking (and the like) easier, but I often have a hard time detaching myself from the (very) personal experience a book ends up being. I don't just mean the contents of it, but also the feel of havin…
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).
