PSP Go that should land squarely in your wheelhouse. First unveiled during a Gamespot UK unboxing of the new handheld (around the 10:00 mark), the Go allows players of any game to save their progress and perform other functions on the device. Upon returning to the game, you can instantly hop right back into whatever it was you were doing at the time of your save.
In the aforementioned unboxing video, Gamespot UK's Guy Cocker saves his progress during a Motorstorm: Arctic Edge race in order to watch a trailer for Motorstorm: Arctic Edge. Rarely do we get urges to watch trailers for games we're currently playing -- but we suppose we've succumbed to stranger impulses before.
