First time out of the vault

I use Windows 7
I used to be a sys admin (started with NT4) and at the time of WIN7 lunch I hated it, i found it excruciatingly uncomfortable. However, time proved that most of the things that held me back were habits, I got over them and currently Win7 is the only sys I am running on my home computers. In my experience WIN7 preforms better even on older PC\laptops.. (as you can use diskonkey to extend memory)Where is Win2k? [Best OS that MS ever produced.]
If not for FO3 I'd be using Win2k. For that monstrosity, I updated to WinXP [basically going from version NT5.1, to NT5.2 and some bloat]. Only as of this year did I finally get to see just how bad Windows has become, when I updated to [and actually started using] Win 7 for anything productive; it was because the Blender dev team abandoned Windows XP.
*Win 7 is a pain in the ass; win8+ doesn't count as an OS IMO.
What else can you do on PC except for gaming?Arch Linux. I'm really comfortable with it now, and I only boot Windows for music production (couldn't get Ableton Live to work with Wine) or gaming (which I rarely do nowadays - yes, I'm waiting for you, Hearts of Iron 4).
Has anyone gotten that Windows 10 notification on their desktop asking you to upgrade to the newest version? I'm kind of skeptical, is Windows 10 gonna even be good?
I am not sure what the plan for Windows 10. But Win7 was also free-ish, at least its beta version was. I know a person who said that instead of upgrading\buying, he kept using it for years after for his casual use laptop and the updates kept coming.It's interesting that Win10 is offered as a free upgrade for now. As far as I've heard, all future versions will also be free once you have Windows 10.
Interesting what it means for us?Windows 10 is intended to be, at least for the foreseeable future, the "final" version of Windows. Microsoft intends to switch to putting out smaller and more rapid feature updates so that new stuff gets rolled out more along the lines of smartphone apps and OSes, instead of as major OS revisions you need to purchase separately.
