The iPaq does have a relatively large display for its size but it is a relatively small device. I like mine as well because it slips into a pocket. My eBookWise works better when I know I'll be reading (iPaq in my pocket, eBookWise in my backpack).
Color doesn't matter much to me one way or the other. One problem with the iPaq, though, is that it doesn't offer especially good outdoor daylight viewing. In contrast, for whatever reason, the eBookWise does seem to. (So does my ancient Palm IIIxe which is a great little machine that you can often pick up for almost nothing).
I'm not married to particular devices but Compaq made a really nice PDA. I wish that the PDA market hadn't crashed.
