So after downloading the files three times, first time yesterday, then when opening the Get W10, it downloaded it again while I wasn't looking, it stopped responding so I restarted the Surface and guess what, it downloaded it again. But now it's installed.
Mixed feelings so far, if you wander off to desktop part while in tablet mode, you cannot open the virtual keyboard, you have to switch to desktop mode.
Pinning of sideloaded apps to start is not working in tablet mode, guess what, switch to desktop mode, it works there, and switch back. Looks like in W8 they neglected the desktop, so it was the touch part's turn now.
And OMG, they killed the charm bar. The bastards! Which means minor logistics problems if you want to open the old app's settings.
Edge does not take over IE/ Internet settings. I have configured restricted sites in IE, they still work in IE, but Edge is ignoring them.
So nothing without a solution so far. All things that I can live with, but I hope they will fix them, soon.
