The upgrade for MS Surface Pro was smooth. All the VST instruments in the Surface Pro played fine through a USB 3.0 multiport and Asio4All. Windows 10 seems to have improved in the area of latency, too.

I had to reinstall the driver for the iConnectaudio4+ connected to my Lenovo Yoga after the Windows 10 upgrade. Everything is good now. I like the new interface and of course the powerful Search feature.

It seems that Windows 10 came in at the right time for you. You will have lots of choices with touchscreen which your MacBook Air doesn't offer. I like the touchscreen of my Yoga 13.
