It's the old problem of form factor. It's why I'm not interested in a "converged" device that is cell phone and PDA. Some of the things I do require a larger screen than a cell phone is likely to have.
My reader of choice is a Palm OS PDA with a 3.5 screen in 320x480 resolution. Depending upon reader and font, I can get about 25 lines of text per screen, or about 400 words, and I'm comfortable reading on it. By turning the back light all the way off, I can read it outdoors.
I shy away from the current dedicated readers because I need color, and I need a device that does other things besides display ebooks.
I'm not interested in an iPhone, but if I got one the iPhone port of eReader would be the first thing I'd put on it.
