"You ever use one? Unless you had it laying down and used it like a piece of paper, I would prefer a tablet."
exactly. my mom has one, and i've used it as i would a notebook computer. actually, very literally, much more like a laptop.
but its a bimodal sort of thing: if i'm using the keyboard alot, i'd prefer to just use keyboard shortcuts. if not, just a pen works great.
but i guess its all an issue of taste, etc.
the drawback of any kind of pen (with or without lcd) is taht you need to put the pen somewhere while you're using the keyboard; with a mouse, at least its right there ...
