Wish I could use it
Tried updating a Lenovo Yoga S 12 from Win 7 Pro to Win 10 last week and it was a complete disaster.
Loads of drivers missing, software telling me it won't work any more and even my Bluetooth mouse wouldn't connect. It would have taken hours to get the machine in a workable state again and that's not on for most people. I took an image beforehand just in case and I definitely needed it.
It may be fine an a brand new machine, however until they get the basics of upgrading right I wouldn't hold out much hope for the rest of Win 10.
