My original PSP "Phat", the first model. It's a fantastic device that I've had countless hours of fun with both thanks to some great games and some really magnificent homebrew. I installed custom firmware on it the day I got it (I think it was 3.03oe-c) and the themes, emulators (built in PSX emulator that works flawlessly with virtually all PSX games, full-speed SNES and Genesis emulation and a now decent N64 emulator), custom shells etc. makes it rank as my all-time number one technology gadget.
