Sony gives more info about PSP
Sony has been talking about the PSP, its portable games console that\'s already being touted as a potential GBA beater, even if Nintendo is being characteristically blase about the challenge. Amidst reiterated details on the handheld, a few new factoids have come to light.
The PSP will feature a wireless LAN capability apparently, while the Central Processing Unit is almost ten times faster than that of the PSone. The PSP will feature a similar button layout to the PS2/PSone control pad; the unit itself will make its first public appearance at next year\'s E3, though games for the console aren\'t due to be demonstrated \'til Autumn 2004. You can check the full specifications of the console below.
