You probably wouldn't buy a PlayStation Portable games console to use as a phone, but if you carry one around anyway, you might just be interested in using it as a Wi-Fi videophone. The press release says:
BT and Sony Computer Entertainment Europe (SCEE) have signed a groundbreaking deal to transform the PSP (PlayStation Portable) gaming device by adding wireless broadband communications functions, including high quality handheld video calls, voice calls and messaging.
It's a four-year deal with the roll-out starting in the UK. SCEE operates in 102 countries (and it could be many more before Yorkshire finally gets home rule) and is shopping for deals with other phone companies to reach new markets.
