Back in the days of Vista, I had been dual-booting and using Knoppix (Live CD) as needed for a while. My main daily use outside of games was all open source that was available on Windows and Linux, OpenOffice (would recommend LibreOffice now), Firefox, Thunderbird, etc.
Windows used to get dreadfully slow, unless you reinstalled. Or maybe I was fixing something. Reformatted the hard drive, set up the Linux partition (Ubuntu 6.06 IIRC), Synaptic, tick all my usuals, apply. Come back a little bit later, fully up to date, do some logins, Linux is fully usable. Even installed Battle for Wesnoth in case.
Boot over to Windows, update, reboot, update, reboot, install drivers, more reboots. More drivers, more installables, more updates, more reboots
It was bedtime, off finish off later, and I ended up using Ubuntu as my main for a week.
After that week, I found I only booted to Windows for games. Never looked back. That week is the week I flipped from 60%/40% Windows/Linux to 60%/40% Linux/Windows. Since then Linux only gets better, and I use Windows less and less.
