what's the point of this ?
I'm gonna skip on the Windows 10 opinion, so much of it having been written.
But, I'm really asking myself why MS spent even a 2 liners' effort for W10 on PI3 ...
The PI being essentially an enthusiast only system (your grandpa, grandma, old grandaunt or whatever captive user that never envisaged others OSes than Windows were even possible in all Universes, is never gonna buy a PI), why is MS even bothering with W10 ?
I can only see 2 reasons: beyond speakable despair to get coverage, or the need to add one more slide to pointy-haired bosses pres about W10.
