The best selling consumer electronics device ever was a Nokia dumbphone that sold over 250 million units (probably well over that since the last reported data). I'm not sure if the fact that DS is split into three models makes it not so comparable, but I'm interested how it ranks among consumer electronics devices generally.
If you combine all iPods, which vary wildly from the early ones to the newest, they're at over 260 million, but aside from that what else beats DS?
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
