So, I've been running Windows 10 in a VM since day 1... and have not run It on real hardware.
After my primary drive started flaking out, I went out and bought a new SSD, and decided to just bite the bullet and install Windows 10 as my primary OS and take all the associated risks.
So far, i'm really enjoying it. It's very fast. Edge (Spartan) is working well. I haven't even bothered to open IE for anything yet.
The only issue I've had was that initially, Windows 10 didn't detect my NVidia GTX 650 and only one display was available, but after a windows update and reboot all was fine.
This is actually feeling pretty solid to me. We'll see how it goes after the next upgrade.
