What computer OS do you use the most?

Also, for the first time in my life I have a legal OS in all my computers...

Lol, now that you mention it, it's the same for me too. As of three weeks ago, when I switched away from XP.

Win7 at work.

I had a dedicated Mint machine I was running at home but it developed more hardware problems than I felt it worth it to fix. I bought a W8 box intending to dual-boot it (Mint DD, Win8 as necessary) but I got sick of reloading the Windows partition due to corrupted startup files every time I booted into Linux before I figured out how to keep that from happening...So I'm DDing Win8 now. The remaining Linux boxes are obsolete and on light duty.

Windows 7 at home and work. I have a Macbook Pro that is 8 years old now and still kicking, though the wife only uses it occaisonally since I have a former work laptop that is Win 7 too.

I use Mac at work with the new job.

So here's the breakdown of my current computer situation:

My work desktop: Windows 7
My work laptop: Windows 7
My personal laptop: Linux Mint / Windows 8 (I use Mint way more than 8 because it performs a lot better)
My newer desktop: Windows 7
My older desktop: Windows 8

I guess that makes me mostly Windows, but I use Linux a lot more than some would expect.

^^^ Nice! What version of Linux Mint are you running? I'm running the Mate desktop and love it!
