I bought a surface pro 3 with a dock - the only time I've splashed out and bought what I thought would be high quality hardware. Win8 was okay but 8.1 really set things on a good track. I couldn't believe all the ridiculous press about how awful it was. But Microsft obviously did and now I have win10 - one of if not the worst OS's I have ever used - on hardware that is also complete junk. The dock loses connected drives all the time ie many times a day. But at least the net doesn't disconnect itself all the time now like it used to. And the screen has fuzzy yellow bars down the sides now. Windows 10 was a complete step back in usability - why for instance did they completely change the way you could snap screens? Onedrive is junk - today I had a repeated notification that I couldn't delete OneNote links from Onedrive. I mean every couple of seconds this notification appears. Puzzled me as I don't use Onenote, hardly use Onedrive and have done nothing to change anything about them. Getting rid of those notifications was not trivial - in the end I disconnected Onedrive sync and deleted all the files. But I am not going back to dropbox - instead when my current projects finish in the next couple of weeks I am taking advantage of the very good replacement guarantee for the Surface Pro and sending it back because of the screen problem, getting the replacement, then selling it and buying a Macbook Pro - and I hate Apple as a company. My years old desktop could edit video in Premiere easily - on my Surface Pro - t can barely play across a single jpeg, let alone an actul film clip. Hopeless..
