Don't have a MAC in the house, but still use Airport Extreme
Bought the Airport couple years ago. Setup was a breeze since I didn't have to touch it. It confirgured itself. Used with Windows computers, but now retired and use it with Linux computers. Works extremely well. Untill my daught in law's tried to play games, and he told me the games were blocked. I setup his computer and I didn't block them, so guess I'll need to look into the issue. Just wanted to say, if the Airport EVER dies, I will most certainly buy another.
