The camera isn't the best if you're planning on clicking pictures for any purpose other than viewing them on the phone itself, and the mp3 player has its drawbacks, but if the handset design matters more than those features, it's good to go. The Nokia model Sudeep posted above seems more feature-rich, and the dimensions seem to be right too, that could be a good choice if price is not an issue.

It doesn't carry a review of the E200, but does have one of the E250, which is basically the same interface software on a slider model : http://www.mobile-review.com/review/...-e250-en.shtml
