This is why I'm excited about the new Nook, it's eink but has the ability to backlight itself when needed to be read at night, but still has the eink benefits when read during the day. Mind you that one's $139.

Only reasons I haven't already got it was some EXPENSIVE surprises recently mixed with kinda hoping they take one more leap in features within the next year to make the upgrade from my regular nook just a bit better.
