PSP
Playstation portable- Sony's entry into the handheld market, and a good one at that. Was released in North America on March 24th 2005. Was Released Japan in late 2004 and came with firmware 1.0 while NA psp's were unfortunately upgraded to 1.5, since a 1.0 psp could run homebrew applications, and Sony's decision to restrict this was stupid- seeing as it could essentially be a Nintendo Revolution killer- free emulators portable? Runs umds (universal media disks) and memory stick duos.
