Summary: Out of the Cyber Shot camera phone family, I've owned 3. The k790, K850, and now the C905. Each of these three phones were ahead of their times and the latest entry into the Cybershot line is no exception. The C905 has taken everything that the 850 had problems with and revamped it. I personally love this phone and plan on keeping it for quite a while. The music player is very solid and the camera speaks for itself. Wi-fi and 3G speeds could be a bit faster, but for an unlocked phone it is fantastic. (better than my old k850)

This phone is much more solid in construction than my previous phone and the slider opens up with a very satisfying click. The number pad is flat, and could use a bit more tactile button set-up because the flat buttons make it hard to text sometimes.

All in All, if you have the money and need a new phone and digital camera, this phone is the best investment for a 2 in 1 piece of tech. You won't regret it.
