Sony has built a great franchise with the PSP series with PSP Slim and now PSP Go. Granted, the PSP series is in danger from Apple and its iPod touch that’s trying to displace Sony and Nintendo’s mobile gaming consoles, but there will always be a soft spot for PSP for hardcore mobile gamers. That’s what the Sony PSP Go promises to do – bring a new flavor to mobile hardcore gamers with a completely new style.

CNET writes, “Sleeker, slimmer PSP design; 16GB of internal storage; expansion slot for additional memory; Bluetooth connectivity; good integration with PS3; can access multiple downloaded games without needing to keep bulky UMDs at hand; you can pause and resume game states.”

However, “Pricey, despite lack of touch screen and second analog stick; smaller screen (but same resolution); awkward placement of analog stick, volume, and display controls; unable to play UMD games or use old PSP accessories; uses obscure and expensive Memory Stick M2 format for memory expansion; battery not user-replaceable; slow download times for large games; online store not as intuitive as others (like the App Store).”

In conclusion, “The PSP Go is a sleek and sexy redesign, but its high price tag and some frustrating caveats mean it’s not a must-have upgrade for existing PSP owners–at least for now.”
