Maximum PC: We had the opportunity to get our hands on the Razer Edge, which Razer is advertising as the most powerful gaming tablet in the world. Our particular unit costs $1,450 and is armed with an x86 i7 CPU and a discrete GeForce GTX 640M video card. No integrated graphics and ARM processor here, folks: This is a full PC. Watch as we unbox the device and it's various peripherals (console dock, controller extension, and more).
Oh, and if you wanna go all out, get the new Sony Z. You get playstation games plus it hooks up to your tv which pretty much makes it a console.
You can get a much better PC, it is a nice idea but the tech needs to get cheaper.
