The P800 uses the UIQ (version 2.0) user interface and has a touch screen much like a PDA. It is powered by an ARM9 processor clocked at 156MHz, which was also used for the later models P900 & P910. It came with a 16MB Memory Stick Duo but supports up to 128MB. Also, the touchscreen displays 4,096 colours (12-bit colour depth)

Trivia

A slightly dressed up version of the P800 was placed in the James Bond film Die Another Day.

A P800 can be seen on the street among the wreckage in the movie Resident Evil: Apocalypse
