I have a chromebox pc (cost about 160 bucks) and an android tablet that dual boots with windows 8.1 (costs about 99 bucks).
Both the android tablet and the chromebox work great.
I see no need for windows any further. I am typing this on a windows 7 pc, but when it goes down, that will be the last windows only computer I buy.
As for linux, been trying it since 1999. Always had hardware problems with it.
