The problem is that people are used to a big bright Start button on the bottom left. When newbs first start using Win8, there's no indication that you're now supposed to be using the edges and corners to get stuff to show. Its not at all intuitive.
But again, what do these new OS s do that the old ones don't?
I was really impressed with the new search function of Windows 7. Its not just for files anymore, you can search for functions that the OS performs.
So, say you want to change your screen resolution. You can type into the search box "change screen resolution" and it will pop up with the video settings options.
It seems like it is mostly furniture arranging to me.
There's other stuff that changes behind the scenes too, though. Networking can get easier and more secure. The way the OS implements hardware. Stuff like that that you don't see from your computer chair.
Actually, I just put in a new motherboard in my computer, which runs Windows 7. Normally, that's a whole new build with reinstalling the OS. We decided to just through everything back together to see what happens. Windows fired right up. And it was installed on a Raid 0 on two harddrives. That's actually pretty sweet.
