Hi Everyone, I'm itching to buy a new Mac; and I have my heart set on a 24" iMac. What do you all think of the timing? Is now a good time to buy? Are there any major updates coming in the next 2 or 3 months? Also, can anyone tell me the pros and cons of the 2.66 GHz model when compared to the 2.93 GHz model? Those are the two price points I am considering. Thanks!
