For good and bad, Vita replicates the home console experience. Clunky kitchen-sink OS, huge-ass system updates, overblown games, silly load times. Combining the mandatory system updates, reboots, game updates, intro movie/load screen/Welcome to the wonderful World of Wipeout! bullshit (touch screen to continue! now touch START to continue! now touch CONTINUE to continue!), it was about 20 mins from inserting cart to starting a race in Wipeout.
In game, it is fucking incredible so I can understand why the fans forgive all the other bullshit. But it IS bullshit. This is patently not something you can pick up and play, unless you load a race, then put the system in sleep mode until you are ready to play. If I'd started that process on my (former) morning commute, I'd have reached the office by the time the race started.
