No one ever mentions the
REB1200. It is, in my opinion, far superior to the
GEB1150. Yes, it's heavier but it has a MUCH better screen. I own the 1150 and the 1200 (and a Sony 505) and would never go back to the 1150 after using the 1200. The 1150 screen is dingier, greenish and much duller and is much harder to read IMHO. I also enjoyed the larger screen immensely.
I'll be selling the 1200 one of these days on Ebay when I get a chance to list it. I only purchased the Sony when the new light wedge came out for the reader. The light wedge leave a lot to be desired and it's expensive but I use it everyday. Otherwise, I would stick with the 1200 due to its backlighting. Say what you want about e-ink, the ease of reading in the dark without an obtrusive reading light is my first priority.
