The grapevine says Microsoft has acquired at least several hundred
new Pi mobos, so it seems Redmond really is actively trying to get the Win10 OS onto an SD card for the ARMv7 sometime soon.
Apparently, it is also not
going to be some sort of RT castoff. Nothing has been said yet about the things that are usually needed to make windows machines practical for the mainstream: antivirus programs, printer drivers, touchscreen interface, etc.
This means something of a coming seachange for the Raspberrian/Linux Users
as they can easily feel this is an unwarranted Humpty Dumpty intrusion of proprietary programs and (I quote) "moronic mainstream users"...
I better point out that The Raspberry Pi Foundation has supported the addition of Win 10 to our available OSs. (So please keep any fanboy anger from either side to a minimum.)
Now is an opportunity to let Microsoft know what you do (or don't) want in a Win 10 feature set- for example, they prob'ly don't yet even know the extent of the various Pi communities, like the DIY crowd.
Remember, Windows 10 will be removable with a click of an SD card. That works both ways.
For me, I'd like Microsoft to be respectful of all that has been accomplished here, and even generate a 'linux mode' to support the coder's original mission.
