Come now. The PSP is worth a very respectable hundred bucks towards the purchase of a DS Lite. That's more than twice as much as the SP. If that's not a selling point for the PSP, I don't know what is.
In all honesty, that poster almost makes me feel kinda sorry for the PSP. The poor little handheld looks so ashamed of itself. I kinda wish they'd attach a Phantom of the Opera mask to the front of it.
