Given what we know about the state of computer technology, how much better could the fabled "to be released any day now" iMacs be compared to the top of the line iMac currently available? Is it reasonable to hope that any new iMac is going to be substantially better than 3.06 GHz, 24 inch, 4GB RAM maximum, Nvidia graphics, etc, etc? I've been waiting for the "new" iMacs to appear for quite a while now, and frankly, I'm getting sick of waiting. I've already decided I want nothing less than the top of the line iMac in its current configuration. By waiting for the new line up to appear, am I just fooling myself into thinking that they will be substantially better than what is available now? My hobbies are digital photography with Adobe LightWorks/Photoshop, and HD movies using FCE, and I also dabble with music creation using Reason. I'm reasonably sure the current top of the line iMac will be able to deal with all of that.
