I like Windows 10, it's a lot like Windows 8, but better.
We've never seen that before from Microsoft

As for linux. I tried ubuntu a few years back. I found it enjoyable, but the deal breaker was of course the lack of support for the OS by popular apps like Microsoft Office and Starcraft.
You have to run it through wine, but that's a band-aid solution. It usually results in a bunch of problems.
