Seeking a Good eBook Reading Device?

Quimbly asks: "I'm an avid reader, and I find that downloading books is much more convenient that trying to get them from the bookstore or library. However, I'm tired of sitting in front of a monitor to do my reading. I'm looking for a hand-held device to do my reading on, and I'm hoping the community has some suggestions. It seems to me that most PDAs have too small of a screen for convenient reading, and a notebook / tablet computer is too big and bulky for this simple task. So, I've been looking at a few devices designed specifically for eBook reading (e.g. the RCA REB1100, the eBookwise-1150, etc.). These look more promising, but I was disappointed to discover that the RCA device ONLY reads an encrypted, propriety eBook format, making it essentially useless. (Has anyone ever hacked one of these?) Similarly, I believe both of these devices have been discontinued by their manufacturers. I want a device that can read a variety of file formats, especially scanned, non-text PDFs. A large screen, long battery life, and good interface are other attributes I'm looking for."
