Good show on the Ubuntu! That will give you a great operating system to play with, and learn a lot of things. I found one of the great packages to download for it is ‘synaptics’ and that will expose you to all the software that is in the repositories. Just don’t let it get too far behind on releases, if you plan to do upgrades.
I still run Win 7 as my MS OS of choice, altho I do have Win 9 up here. (And inside that, the Win 7 beta.) And just yesterday I got a nice small thing that came with ‘Windows 8.1 with Bing’ on it. (Can you believe Microsoft is almost giving that OS away?) I think I will try and keep that from all the fixes for the ills of Win 8 and maybe see if I can get to tolerate it.
