I just ordered a new iMac 24" 2.8Ghz yesterday and now getting second thoughts! I keep thinking to myself if I should have waited for MacWorld in January. Why is this drving me nuts! Maybe I should buy something older, this way I don't care about the new. What is the best way to stay on top of the Mac update wave? Update: Also, has anyone have experience with the wireless keyboards and mouse? I ordered my computer with the wired keyboard and mouse but now I feel that it would be nice not having to deal with the wires. Is there any advantage to either of them?
