[Jinnai]

I don't really need the newest thing out there unless its some kind of godsend. My big concerns are reading manga and using it for my role-playing books (so i don't have to carry 20+ pounds when I go gaming).

I do have somewhat bad eyes and need to have things closer to me in order to read, but eyestrain has never been an issue for me. Basically I can't read small fonts like 10pt and some 12pt easily.

I also would likely be reading a lot more in the dark, such as on trips, than outdoors or in brightly lit places. I'm not sure how bright you need it to be for some ereaders without backlights.

Color would be nice, but it isn't a make-or-break item....mostly my ability to read manga easily in almost any lighting condition and with a decent battery life. I would prefer a responsive touch-screen interface as opposed to buttons since there's a good chance I will need to zoom in/out in for reading text and then to see images fullscreen my experiences with my modded PSP aren't exactly the best.
