The only time I play portable games is when I'm on the couch, and with a wireless controller and a trip to the PS2 to turn it on, it is as convenient to play the PS2 as it is the PSP.

If you play your portables outside more often, and don't get to play your consoles too much, then probably bringing a PS2 on a portable makes sense.
