hrm, I wonder...I have noticed on my travels the ubiquity of non-Google Android devices. I wonder if the value of *those* is doubled.
I am, of course, assuming you mean, by 'base Android', the one which is installed on Nexus devices - ie it doesn't have all the manufacturer-added software? If you instead consider 'base Android' to be what is available for free, then perhaps it does indeed add value since it is otherwise quite simple, constituting just a platform.
I think people in 'the west' seem to think Android is only the one that has the Google services/apps/etc, since that seems to be the only one available. In China, for example, I've yet to see such an Android device, and yet there are plenty of non-Google Android devices...perhaps the s/w added by Samsung is adding value to *those* devices.
Of course, that wouldn't excuse them from also adding the s/w to the devices that *do* have Google services/etc...
I'm not sure if my suggestion is actually the case, just wondering.
