I'm not sure. At least for me, part of the charm of these older consoles (do they qualify for the "retro" term yet?) is the smaller resolution of the displays. Especially for the bottom screen on the DS line, there is something very warm, fuzzy, and cosy about clearly being able to see each individual pixel.

Perhaps it's just nostalgia. I still own my DS Lite, though.
