Though I love ol' Phats, many of my PSP-1000 frustrations comes from the design flaw that is the WLAN switch on the side. I'd often just graze it and suddenly get disconnected from a multiplayer game session and in most cases, even with the switch on, the system keeps telling me the switch is off.
With WoL being a PSP-3000 and having almost exactly the same design as the PSP-2000 with it's WLAN switch on top, replacing the old IR spot (which was a stupid idea in the first place) fixes all my gripes with PSP multiplayer.
Finally I can wail away at the buttons without fear of getting disconnected in a game.
Note that my Barts was 10+ levels weaker than the Cloud I was facing. [youtube http://www.youtube.com/watch?v=pPF98rmtz8g&w=560&h=349]
