Loved the PSP!
It had some of the best handheld games I've ever played (ie. God of War, Metal Gear Solid Peacewalker, Crisis Core Final Fantasy 7, Kingdom Hearts Birth By Sleep, Monster Hunter, Grand Theft Auto, and of course a large library of PS1 classics)
And I loved that it was a video/music player as well.
I even got the PSP Go. I took that everywhere and then docked it and played on my TV w/ DS3 controller.
