Months ago it was announced by Google that Android phones were selling at a rate of about 22 million a year already. And Android's marketshare has been doubling every quarter for the past year.
At the incredible rate Android is growing I have to imagine it is currently selling at a much higher rate than 22 million a year now.
When Novell sold out to Microsoft you had open source kooks falling all over each other to proclaim that they would go right on using Novell products and projects so they could brag about how 'open minded' they were to the rest of the world(who didn't give a shit one way or another).
You have to imagine the execs up in Redmond were just shaking their heads in disgust that they had disrupted the open source/Linux world with so little effort.
I don't think Microsoft is really actively wasting time with Ubuntu. They don't have to. Linux marketshare is going nowhere outside of statistical blips. They have Miguel de Icaza doing so much damage to desktop Linux adoption and application development with the Gnome/KDE split and the Mono fiasco that they surely must be entirely focused on Google and Apple(commercial companies run by grownups and staffed by competent people who put in 40+ hour a week work on the unglamorous work that goes into creating polished consumer ready software).
An Ada exception is when a routine gets in trouble and says 'Beam me up, Scotty'.
