I waited all the way through the winter of 2013-14 until now to buy a new iMAC on the expectations that a new generation was about to be born. Now I learn that any new iMAC awaits the new chip development that has been stalled until at least 2015. What to do? I have a 2006 iMAC. It works great and has some features that match my other devices - such as external hard drives, modem etc., that the newer iMACS have dropped. So I can hang on. But on the other hand, I am ready to replace the 2006 iMAC with a larger screen model and more RAM etc. My question to long term MAC users is, is it worth waiting for what is scheduled to appear next year? WIll the advantages of a faster chip be all that is in store if I wait or are there other "improvements" that are likely to accompany a 2015 new generation iMAC? I ask this because, having a 2006 iMAC, I am not familiar with the advances that have been made since then - except to know that some features no longer exist such as firewire ports and CD ROM drives. It will help also if you can tell me if I can obtain adapters or additional equipment that will facilitate the use of CD ROm dscs and firewire external drives.
