You do realise Vita is region free don't you? It doesn't matter what country you buy it in. I don't get why anyone in their right mind would region lock a portable console.
How do you play racers on a console whilst on an 8 hour flight to chicago? Need for Speed Most Wanted at 10,000 feet was amazing! I also have a 1 and a half hour commute to and from work and so this is why I like a handheld console and also so I can game without hogging the TV. I therefore love that Vita is capable of offering a full blown gaming experience unmatched by any other portable gaming device.
Also if you think Vita hasn't had any western games worth playing in 2013, I have no idea how any console can satisfy your gaming requirements.
