The severe lack of expandability is the iMac's Achilles' heel and I would gladly use all 8-cores if Apple released versions of all their ProApps that actually took advantage of all the RAM and cores the newer Mac Pros can be loaded with.I wouldnt be surprised to see Apple eventually abandon the pro name, and just sell macbooks (which would be current MBPs) and imacs. The high end imac is such a powerful machine that I cant see why anyone would want to buy MP. how many people really take advantage of 8 cores?

other offerings are not an option. Right now I'm still struggling with my 2x2Ghz G5 and am in desperate need for an upgrade. My G5 still works great and I can certain make due with it and get more creative with my workflow to accommodate the speed issue. I personally know several people in this boat including a pro editing facility in Nashville that only 2 of their towers are intel and the manager there has tried to encourage me to "get the most out of my machine and save the $". If I know this many user deciding to deal with their current comps, the total number must be pretty high.
