I am in the same kind of situation. I personally hate both windows and mac. I have no tech rizz, but I ran ubuntu for the last 6 years (before surging currents killed my laptop) as win 8 gave my laptop “cancer”. My guess would be some kind of think pad with a linux distro on it. And don’t worry, if you can use a search function finding a linux distro and installing it is so easy even I managed.
