Ah, I see what you mean. I haven't updated to iOS8 as it requires 5.8GB free storage, and a fast connection on top of that, so I haven't had to go through any of the problems
I see Windows 10 introduces MS's own versions of features on OS X for a few years - as you said, pushing usability and styling forward
I think one thing that seems wrong with Windows 10 is the fact that it's the same OS over smartphones, tablets and desktops. Windows 8 was actually three: 8, 8RT (tablets) and Phone 8 - and
that had people complaining about the desktop version being too similar to tablets - so what will Win10 be like with the SAME OS this time round
