DSi = DS?

[shams]

The DSi can play (most) DS games - but the DS cannot play DSi games.

If DSi only games came to retail, then the issue would get more murky - and they would, in effect be two separate consoles.

The DSi has a *lot* more RAM than the DS does, and runs at double the clock speed. The screens are the same resolution.

I'm not sure about graphics capabilities - if the DSi was capable out outputting double the polys that the DS could - that would be cool.
