Pulled the trigger on a new iMac purchase a few hours ago. This is my first endeavor with an Apple computer (other than my iPhone)...I'm yet another switcher. Picked up the 24" with the 3.06 CPU but, following the advice on this forum, purchased my ram upgrade from Crucial rather than buying from Apple. I also thought about buying used from one of several private parties, but felt like my first adventure with an iMac should include a full serving of AppleCare. If all goes right, the iMac should show up on my doorstep Friday. I can't wait!!! I wanted to take a moment and thank all the folks on these forums for all the great guidance. This leap from Windoze to OS X is much easier as a result of the great advice received from all you folks. Thanks and clear out room for another seat on the Apple bandwagon!
