Kindles (the eInk ones, not the Fire) might be a good push in the "for reading" direction. You really can't do much else with them, but they're really great for reading, as well as super light, and have amazing battery life.

I got a Kindle Fire, and reading on it is just not the same as with the 'real' Kindles - you always have 'other things' like email and Facebook lurking just a few clicks away. And the battery life is something you have to keep in mind, and of course an LCD screen just isn't as nice for reading.
