THE GOOD: 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.

THE BAD: 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).

THE BOTTOM LINE: 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.
