I loved my Kindle so much that I splashed out and got the paper white with built in backlighting. It makes a huge difference to clipping a light and jakes it easier "drop on the pillow."

The battery seems to last as long as my old one too, funnily enough.

What I like best is Whispersynch. It means if I don't have it with me but killing a bit of time, I can open the Kindle app on my iPhone or iPad and carry on from where I left off and vice versa. Train etc.
