If I wanted 2 main computers I would run linux. Since I need 1 computer that does everything.. its windows 10.
If i Had an older computer and needed basic web browsing, etc I would run linux... did they ever fix it so adobe flash works? I remember spending 3-4 hours trying to get it running.
There's been a nifty thing out for a while, called dual boot.
Flash works just fine, and has for a rather long time, too. I can hardly remember back when it was an issue, it was that distant. The last time I had to really get my hands dirty in Linux was around Ubuntu 6.06, almost twelve years ago, and that wasn't even so bad. The upshot was I learned more than enough then to keep me going through any potential emergency I'd come across now.
