Same here. RM2 is probably one of my best investments for research and learning ever. Only drawback is I cannot read it without light at night. Would have been perfect if there was a back light like kindle.
I was seriously considering popping over to their site and ordering an RM2. But no backlight? That's a show-stopper for me - thanks for mentioning it as I think I just assumed it would have one given that most eReaders do.
