> What about lack of all the Linux/OS X GUI software?
Windows prolly has more GUI applications than both those OSes combined. That's not necessarily a good thing but it's not bad either. It just means there is a Win substitute for everything.
> What about lack of all the UNIX OS features?
Same answer as above.
> What about all those billions and billions of Windows malware, viruses, adware etc.
I download a lot of crap on my home Win computer and haven't had a virus once in the past 6 or 7 years. There are likely more Android viruses active now than Windows.
> What about all the spying and restrictions that Microsoft has integrated into the Windows?
If you don't give permission the action is not taken. Granted I am currently getting spammed to update my home computer from win 7 to 10 but it hasn't force installed on me. Likewise for automatic updates.
> What about the fact that OS X and Linux have always been at least decent from developers point of view but Windows has always had problems and then things like Vista and Win8 happen.
Which is what this new initiative is trying to fix.
Don't get me wrong. I love my osx for dev and my *nix boxes for servers. But if I can get one machine/OS for desktop development of nix and windows without having to run silly emulators or switch between VMs then I'm sold.
