Hello, we are new to the Apple community and the iMac computers, we have just bought a iMAC 20" 2.66 with 4 gigs of ram and a 24" iMAC 2.8 with 4 gigs of ram and the 500 gig hard drive. We have a lot learn as we are coming over from Windows. I have built the last few computers we have had, but I am tired of the never ending updates and crashing of windows. So far I like the iMAC and the MAC operating system, I still have to learn how to find files and folders and such but in time it will come. I am sure I will be asking some questions as I go so get ready.
