Windows 8 is mostly a new user interface on top of Windows 7. If MS would give us the option to make the desktop the default and give back the Start button for desktops and laptops, it would be OK, but I sure wouldn't recommend it otherwise. When MS takes a productivity tool and make millions of folks have to reinvent the wheel, it reinforces my suspicion that their management is out of touch. I predict that Windows 9 will add the start button back and give us the option for the desktop by the end of 2013 - time will tell. When they see how poorly Windows 8 is selling, maybe they'll start paying attention to their customers. We'll see.
I have installed Windows 8 64 bit on a virtual machine so that I would have access to it to support an ISP that I work for. Customers call in and need to know how to setup email, connect to the network, etc...
It seems that the things that I like about Windows 8 are already present in Windows 7, background switching, clean look, seems stable, but the things I don't like are directly related to the tiles and Windows 8 UI. Full screen apps, being the worst, IMHO.
But the main thing for me is that the guts of Windows 8 do not seem that much different from Windows 7. Aside from the ability to run on a tablet with a touch screen or phone, with a smaller screen I do not see the benefits.
So what I'm asking is for feedback from the community at large. What do you like, what don't you like, and what do you not care about in Windows 8?
