Everyone is buying them. Older people, women, children, etc. So the demographic is -- everyone. yes, it has GBA support (PSP has PSX support btw [kind of] and better [easier] homebrew support and a built-in web browser), so I think your point about that is easily mooted, and yes, nintendo has major brand power -- they know what the hell they're doing and how to make a good, solid product that stands up to customer demands, as well as how to mass market their products. I own a single gba game (simply to fill slot-2) and most people I know that own a ds do not own any at all. I'm not saying this is always true, but from what I've experienced, it is very much true. As for the price point, that's absolutely true. If the PSP were cheaper, it would sell much better. However, it's not, so it isn't -- there's no use focusing on "what if's", since "what if's" are simply speculation. You could also make the argument that DS (or even the Wii) are incredibly fun and available to people of all ages and incomes. The PS3 & PSP, while I'm sure they're fun and all (not that I've gotten that from my experiences with them), simply don't have enough good games (compared to ds) and their prices are just too high.
