M$ Lost me back in 2001..NEVER going back.
I started using Linux way back in 2001, as I was already fed-up with m$'s software quality, lock in tactics, and bullying nature...not to mention what happens to m$ acquisitions...
M$ kills everything it touches.
Skype used to be the world leader, and worked well on Linux...now...it's unusable.
Anyone even remember Danger?
Navision is just gone.
AQuantive got written off in 2012...$6.2B wasted.
HotMail...a hot mess.
LinkedIn is already a sea of irrelevant adverts.
AND OF COURSE: NOKIA....need I say more?
I've been a Unix and then Linux and Mac OS X user for decades...m$ is a negative force, and has held back computing progress by 10 - 15 years because it can't stop trying to put everything in a windows straitjacket, despite the fact that the windows architecture is prehistoric, doesn't network well, is bad at scaling, is woefully insecure, has poor file systems choice. I cite as support, the fact that the unstable Azure needs Linux to run reliably.
My company, a small startup, uses GitHub at present...but not for much longer - I don't trust m$ even slightly, and will move ASAP.
