Like Phil, I also find it easier to handle than most books. I can position it on a knee or a sofa arm, and it balances, freeing my hands. I can also read more comfortably when reclining, because I don't have to use both hands to hold a up a heavy book. Battery life is also excellent, especially with wireless turned off.
The downside is that, when flying, you have to turn if off during take off and landing. It's about the profile size of a hardback, so you can't toss it into a small purse. I don't mind carrying a larger purse though--more room for more junk.
