Horace Dediu's latest article ("A new way to value Apple", http://www.asymco.com/2011/07/18/a-new-way-to-value-apple/) gives some suggestions that Macs, iPhones, and iPads represent upwards of $225 recurring revenue per user to Apple. All iOS users are worth about $150/year/user (http://www.asymco.com/2011/06/30/how-much-is-an-ios-user-wor...).

Finally, his Rawr Chart (http://www.asymco.com/2011/05/18/the-rawr-chart/) shows profit per phone sold. The picture isn't pretty for non-iOS devices. It's not quite answering your question, as it doesn't break out Samsung's "feature" vs Android vs Bada (as an example), but the best example is HTC -- which appears to be just under $60 profit per phone (and IIRC HTC is mostly Android, isn't it) with less volume than Apple (which makes ~$275 per iPhone sold).

EDIT: small clarification. The Rawr chart doesn't break out handset maker profits by phone classification, so only Apple and RIM are the only ones who have profit for smartphones only, and maybe HTC. The others have diluted information because they sell more than just smartphones.

That is a great resource halostatue, and they do a great job of explaining the revenue per device figures for iOS.

Compared to this article http://aseidman.com/2010/05/65000-new-android-devices-ship-e... which estimates that each iOS/Android user is worth only $2.64/year/user. Though I'm not sure I trust the authors methodology, and that number seems extremely low.

Your right I don't have the figures and would be interested to see them myself. Generally search marketing is very much a volume thing, each user makes a small amount but having something like a billion users creates a lot of money overall.

With Apple they get a nice markup on the device itself and 30% every time you buy an app or take up a subscription.
