Yeah I’ll be getting that. The DS is far better than the PSP in my eyes, games are much better, the console is pure genius.
Its great to develop for too, costing a lot less than PSP. Much faster to bring out a title. At the moment my biggest challenge with the DS is trying to get Stars in Super Mario 64 DS!
The cartridges are tiny. There slighly bigger than a postage stamp like! There could be a few problems with this add on now though. It could be heavy on battery life and the sound out of the DS is really low too, even with headphones.
