A few notes - Android operates in a fundamentaly different way so these comparisons are apples and oranges. When you talk about the open Android, you forget the 'flavor', the things vendors (do not) put in. Just because something is Android based, that doesn't mean you would not have kernel driver issues, potential lack of source of it's Sense/Blur/YouNameIt interface, etc. Also, Google's cloud services seem to liberate them from open source expectations, as if something executing on a server makes the source irrelevant. Well, if I need to call a web service in blackbox fashion, it IS as bad as a binary blob (in fact, it's a bit worse, as at least the blob can't be taken away from me as easily). Thus the bottom line is you should be comparing generic Android with generic Linux, and (service backed) vendor implementations with other vendor implementations.
