Ok, I have to ask...
So when can we see Oracle suing Baidu ?sp? or now Amazon for running Android forks?
With respect to your flashback to the 80's (actually late 70's to be a bit more precise...)
You had 6800, 6502, 8080s (Z80s and 8080-A) chipsets.
Each with their strengths and weaknesses, each coming from a different vendor.
Do you see that happening with different fragments from Android?
Amazon could frag off a distro and make it their own, and license it out again.
Android is licensed under Apache 2.0 so Amazon can do a lot of things.
So outside of Oracle's battle with Android... would you really trust a distro from a non-Google source?
