Switching To iMac

It's different, and you'll have to relearn a lot but it's not that bad and you'll probably notice a general improvement in your computing experience. In my case I found that after a few months OSX felt natural while Windows no longer did but the first month I relied on having a virtual machine of Windows running on the Mac to get work done. The main thing that was holding me back was replacing different Windows programs I used and if you have any questions about that let me know.

I have an iMac for about 5 months. I would not go back to a p.c.

There is a learning curve, but I found, that within about a week, I was able to be pretty comfortable with the differences in the computers.
