And a strong no thanks to a rented OS. I see the various flavors of free Linux as a big stumbling block to this idea.
Windows XP / Office 2003
Windows 7 / Office 2010
Windows 10 / Office 2016
The XP/Office 2003 disk is so I'll always have it and Microsoft can no longer screw around with it.
The Windows 7 / Office 2010 disk is my primary OS and the one I use 99% of the time.
The Windows 10 / Office 2016 disk is so I can view the shambled mess that Microsoft is creating and try and find some way of tweaking it to make it half way operational.
But there's no way I'm migrating to Windows 10 full time, even after 7 is no longer supported. I'm fooling around with Linux distros now and am trying to find the best one to use. I'll likely make the jump to Linux full time within the next year or so, but I hate to do that just because MS keeps putting out a worse operating system than the one prior.
I'm like you, no way I'm storing anything in the Cloud, and all of my files are stored locally. No way I'll "rent" software and if they don't like it, tough. I'll keep my old software, i.e. Acrobat, Photoshop, Office, etc.
