^^ this. Plus Android for mobile.
I find myself using Ubuntu for desktop/laptop for my day to day computer use tho. And windows exclusively at work.
We have 7 comps at this house running Win7. Another one in Michigan that runs Win 7.
One Kindle Fire, and one Galaxy S3 running Android.
One iPad, one iPhone 4, and one iPhone 5 running whatever shit OS that Apple runs.
So Win7 is king here.

Yeah it's called Income Tax Return time for the poors.
