The argument can be made that dedicated portable gaming machines are on the way out, but if they are, they're going down swinging. Take the Sony PlayStation Vita ($250) for example. This replacement for the PSP features a five-inch, 960x544 OLED multi-touch screen, a quad-core ARM Cortex A9 processor, built-in stereo speakers, microphone, front and rear cameras, a six-axis motion sensing system, compass, Wi-Fi, optional 3G and GPS, a multi-touch pad on the rear, Bluetooth, a memory card slot for expansion, and all the controls you could want, including dual analog sticks, the classic PlayStation action buttons, and shoulder buttons.
