DS gets so much support because there are so many more 11 year olds that play games.
The largest gaming demographic is 18-34 year olds. Nintendo may own the 6-13 demographic (mostly with their Gameboys) but they don't barely dig in to the older age group *as much as Sony or Microsoft* (not to say they don't at all). That's why those companies sell more consoles, especially in the US.
However, the DS is changing that for Nintendo as it has already attracted an older average age than the typical Gameboy age- around 17 or 18 years old, which is a great move for Nintendo because it seperates who buys their Gameboys and who will buy the DS.

PSP will get PLENTY of support once the PS3 comes out, seeing as it will feature tons of connectivity.
R.O.F.L. ROFFLE.

That's hilarious because... connectivity didn't do jack **** for Nintendo, and nearly EVERYONE has put them down for ever touting it as a fair gaming method (especially Sony and Microsoft fanboys). But now that Sony has a handheld and might have some features between the PSP and the PS3... it becomes cool? Will it earn Sony any more money or audience than it did for Nintendo? In your dreams.

And to who coughed at Snowboard Kids- whatever, that was a badass N64 game and there are more than enough people who'd like a new Snowboarding game besides the SSX series.
