So I take it that at most this magnifies the graphics of the current DS games.
I dunno how good of a idea this is, obviously for older people such a thing would be great, especially with the brain training software.
But for the rest of us who have good eyes, a magnified screen, especially with games that were not built for it, can make the games you have look a tad bit uglier. So if you are a graphics whore, a bigger DS screen may not be the best thing.
