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.
They could've called it the "Official Sony PS3 USB-to-Wireless Virtual Surround Sound + Stereo Headset," but we're guessing that would have been a bit wordy. Instead it's called the Sony PS3 Wireless Stereo Headset ($100), it connects to your PS3 via a small USB-based wireless adapter, features 7.1 virtual surround sound, a built-in retractable mic with on board volume and mute controls, and a simple, clean design that should match its console counterpart well, whether you're using it to keep from disturbing your roommates or significant other, or if you simply don't anyone to hear the twelve year-old talking trash about your sub-par fragging skills.
