Also, a few more points:
This is just more of an example of Canonical desperately trying to find another, more stable revenue stream. Frankly I could not care less whether my phone bears the Ubuntu logo or the Android logo. The product would be much the same.
I personally much prefer to get my commercial software through third party services anyway, such as Desura or Steam (although I have other concerns regarding steam), but once again I am going besides the point.
