I agree. We bought a little Acer E3-111 for my wife with Windows 8.1 awhile back. It worked just fine. We had some problems with the touchpad recently and I figured, why not upgrade to Windows 10. We've both regretted that decision. It run slowly, and every few days there's new reasons on Slashdot and elsewhere not to run Windows 10. A few days ago I booted Linux Mint 18, Mate edition from a USB stick. Firefox (my wife's preffered browser) started so quickly we were startled and everything was very smooth. I looked at the hits on my firewall/proxy server from her IP and they were down to almost nothing. I'll be upgrading her to Linux this weekend.
