PSP vs GBC watch. I say the PSP can go the distance.

Wait a moment. You're comparing the PSP/PSP Slim and Lite to a single model of the Gameboy line?

The GBColor is still a Gameboy, albeit a hefty upgrade, but a Gameboy none the less.

You also have to consider the last few years sales dropping in anticipation of the GBA.
