i'd let google off the hook if honeycomb wasn't a released product.
are we going to be in a position where we have to stipulate a version number when we describe "open source" android? my guess is google will eventually migrate to a model whereby the latest version of android remains closed, and only outdated versions are available.
at this point i'm not sure why google bothers with open sourcing android at all beyond the perfunctory requirement that they comply with open source licenses for code they utilize. the only noteworthy accomplishment in their open source mobile exercise is their ability to subvert the ideals of open source.
