I had no intention of using it, but we ended up testing it out at work and I've actually enjoyed using it. It took about a week to get used to the look and feel (and the Start menu, formerly called Metro). But, I spend VERY little time in Metro, and have pinned all of my favorite applications to the taskbar. I learned a few cool shortcuts as well for finding other things (the Window key is your friend BIG TIME in Win 8). I'd say I'm more efficient at using 8 now than I was 7.
No one suffers a victory like Gator fans.
