I just got my first iMac couple of weeks ago. I purchased a mid-July 2011 iMac from a seller on Craiglist. Love the machine and it is practically brand new. In the beginning while transferring docs, etc, I had the iMac on the Wi-Fi at my home. Once the transfer was complete, I switched over to the Ethernet connection from my old PC. Just wondering, how many folks use the Wi-Fi option with their iMacs vs. the Ethernet connection. The machine was very fast on the wi-fi connect and was actually thinking of running the machine that way as opposed to the Ethernet. Thanks for any replies. P.S. Might seem like a dumb question but I always associate wi-fi with laptops, not necessarily desktops.
