It's $399 because it doesn't include the camera [0]. You can also use other apps without paying it's $50/year to play multiplayer games / PS+. We'll have to wait a year or so though for it's exclusive to catch up with Microsoft's. In two years when tablets get more RAM and cores, and if tablet games get serious the death of consoles AND handhelds will be increased. After all, unless you have people over, personally I would rather play outside, PS Vita style remotely connected to my PC. So. There. Instant startup opportunity. The closest I've found, is what I use with my PS3 controller [1]. I'm looking for something like the Vita, but for the PC because I'm done with consoles. Unless it gets 10+ games that I'm interested in, there's no point. Who wants to be forced to buy the camera, and be monitored like that. IMO, Japan's morals and culture continues to be the best choice when it comes to gaming.
