Hello - I'm in the market for a new iMac, to replace my MBP (which I love, but never move from the desk). I could realistically live without my Mac (have a PC from work for basic at-home browsing if need be) for about a month. Anything on the horizon that would compel me to wait a month before placing the order? Based on the buyers guide, and other posts on this site...I don't really see a major change coming soon.
