I am so tempted to buy Nook right now, because every time I go to Barnes & Noble, it's the first thing I see. OTOH Amazon has Kindle, and it seems the books will be cheaper on Kindle, compared to hard copies. If I buy Nook, does it mean I cannot use the books meant for Kindle? I would prefer a color version, rather than B&W, but does it really make a difference if I am only going to read books on it? P.S. I vaguely remember that last year there was a thread about this, but I can't find it.
