I'm sorry to say that, tried W8, did not want it at all, thought W10 would bring back a pro GUI, but it's not !
I tried the professionnal x64 release, the start menu shows 10% or less professionnal tools, where is the run button ?
I'm disappointed that the unique flat theme offers almost no usefull customization, for productivity, people need that (the way it was on Windows XP was much better). Can't Microsoft hear that ? Each user has his own way of working, mousing, keyboarding... and needs a GUI where all elements can be resized, colorized... etc. Search on the web for "Change explorer background color windows 7" and you will see what I mean. I hate to have a bright white background, it hurts.
Pro workstations and mobile devices are as different as would be fridge and a thermos. Would you design a fridge considering thermos requirements ?
I can't believe Microsoft is paying attention to users feedback, I believe they pay attention only to their marketing department for whom only market part size matters.
All serious corporations (like banks, government, industry, R&D...) should never accept cloud data hosting nor cloud apps, security & privacy are their priority.
All Unix GUIs were made for pro users, and these users were feeling fine with these. Why didn't you just made a X11-like GUI as Apple did ? What most users (even home users) want is performance, simple actions and customization. They won't upgrade their OS just for some more integrated gadgets and a cloud-binded system. Some may want, I will never.
