This may look like a standard-issue Sony PSP handheld gaming console, but it's not. No, this is the PXP-900, and it is most definitely not made by Sony. But it's still pretty awesome.
You see, the PXP is built as a portable emulator, meaning you can load it up with basically every old school game ever made and play them wherever you want. It's got a 4.3-inch screen and supports "NES, Famicom, Gameboy, Gameboy Color, Super Famicom, SEGA MegaDrive and some sort of 32-bit ROM." And with the dearth of good PSP games, this might be a much more fun choice than the official version.
