I used a Windows 8 machine the other day. I've used OSX the last few years, but used Windows for a couple of decades prior.
I was so confused. It was difficult to work out how to open apps. I also got stuck in the full screen start menu replacement (whatever that's called) and I had to ask for help to get back to the desktop.
Give me XP over 8 any day. Security issues aside, that was a gem of an OS.
Seems like the Microsoft OS team hit the panic button soon after iOS & Android gained traction and have been clawing for innovation without considering actual use cases
