I bought this on a lark. I've had other SE phones and they've been hit and miss. this model is fully developed and works like a champ. Bluetooth integration is strong. Walkman application is great and works nearly seamlessly. I would recommend this product to a friend.One caveat. Be sure to budget for an extra memory card as the 256MB provided will not be enough. The M2 cards are kind of expensive relative to Micro SD but more SE phones will be using so hopefully the prices will continue to trend down.
