I'm a self-employed graphic designer and my 6-yr-old Desktop Pro died. I'm now working from a macbook (not even a Pro. Obviously, I need a new computer sooner than later. I'm interested in the iMac. Yet the buyers guide says to wait, that, according to history, it may be coming out with its next model in 1-3 months. Any guestimation on the accuracy of such reports? And will the new iMacs be worth the wait?
