I'm using my new iMac.
I plugged it in, turned it on, and it Just Worked. It found my wireless network, and connected. At the time, I was worring about where I could set it, so that I could run cables. Apparently I didn't need to be concerned about that.
I still have a few confusions, but I expect I'll figure them out.
Why do I have an iMac? Well, I'm doing a training in May for Big Nerd Ranch and the training machines will be Macs. So they sent me one to practice with, and so that all of my class material will be *sure* to work on Macs. I don't anticipate any problems, but it sure was nice of them.
I really don't have anywhere to put it, but since it does wireless, that makes it a little easier to find a place. At the moment it is on the dining room table, which is less than ideal, but works for now.
