I don't think he's saying that ds doesn't serve all ages. Rather, he's saying that dsi is nothing new compared to the ds, which I kinda agree with. I wonder how many people will upgrade from the dslite to the dsi which is more expensive and doesn't really have any better features compared to the ds, infact, that battery life is teh suck.
I don't see how any of the features will contribute to a better game. I personally have a ds because the games are cheap, there are always used copies, the battery is incredible, and it has quite a few interesting features (aside from the mic IMO).
