I don't think it is that similar, in this case Linux distro model of distributing software makes much more sense.

You can get pretty much all you need in a desktop install of any Linux distribution, or you can ship a DVD or an USB dongle and anything else can be installed afterwards with no problems.

The way I see Android is a platform for consumers (essentially the apps distribution model), and in this case the result is not as good as "have everything you can out of the box".

EDIT: I assumed Internet connection may be limited, but I understand now that it may not be the case. I think my comment stands anyway.
