Summary: Had mine a week now, used it at least an hour a day and the battery not even gone down one bar. Physically beautiful and well-made, I nly wish the page-turn button were a little bigger. Sony's library software is a bit of a poor imitation of iTunes, but not so efficient or flexible. It does not let you edit the metadata like the Apple product, and is somewhat clunky.
Pros: Style, intuitive in use, great screen and battery-life
Cons: Sony library Software is twitchy and prone to freezing, slow transfers.
