I found it to be extremely stable and a powerful performer as both a phone and MultiMedia Device with particular emphasis on 3D Java Games. Its 300mhz Xscale processor simply eats up Mpg4 video rendering with an insatiable appitite for Java Games. 50mb of onboard memory coupled with an external storage capacity of 1GB makes this device ideal for people who like to carry alot of Mp3s and video, or video games for entertaining themselves away from class or work. The built-in stereo speakers and included stereo headphones make the pictures come alive in games or video.
Phone performance is great as you would expect in a high-end device of this type.
