Glenn, the same can be said for NIntendo DS systems. But yeah, I suspect a number of them are dead or retired. Even if we say 1/4 which I think is pretty high, that's still 150M left. It's an interesting stat, but not the end game of course. I'm not sure Apple really cares either so long as they maintain an upward trend.

It came to mind because of a few things that are being handled differently right now. Apple doesn't normally pre-announce products like iCloud and they have never broken down the iPod Touch numbers before that lawsuit filing. It made me reflect back to a thread last year where Matt and I discussed Nintendo DS and iPhone/iPod numbers. I think we were up to around 50k iOS devices which was probably a bit low, but even still, 200M is quite a milestone. Microsoft is celebrating 55M XBOX360 units right now for instance - which are also on an uptick after 6 years.
