ITA! My son has both, and the SP plays all of the Advance games, as well as older Game Boy Color games. The built in rechargeable battey in the SP rules! My 12 year old son has been very patient about gaming systems. He has several of the Gameboy hand-held systems, a Sega Dreamcast with very limited games (terrific system, I wish games were still made for it!), and a Gamecube. He's now at an age where I am willing to get him a newer system, and he seems to prefer the Playstation 2 and it's selection of games. But, I hear the Playstation 3 is coming out soon. Should I wait? Is it that big a difference in the system for a teen? Beorn (ds) has not expressed interest in it at all, but I don't think he even knows about it.
