Ya, installing an insider preview on a new platform, that's just asking for issues. As an early adopter of the Surface Pro 2 and 3, this seems smooth in comparison.
Drivers and firmware are really the culprits of most of the Surface family's issues. I have a feeling things may be rough until a coupe revisions of those have been published. It took about 1 to 2 months to get the Surface 3s ironed out after Win10.
I did and had to revert. The machine kept freezing. Right now my graphics driver keeps crashing when using Edge. But it's better than total system freeze.
