When the Sony Ericsson P900 came out it was a nice upgrade to their P800. However it wasn't perfect, for one thing the P900 needed more RAM and Memory Stick Duo Pro support. It lacked GSM 850 support, Wifi and it still relied on JOT (the handwriting recognition software) as it's main method for text entry. The P910 fixes most of these problems with the exception of Wifi support and the P910a has GSM 850 support.
