when you say "new iMacs"...
I'm going to assume you mean speed bumped with peryn(sp?) processors right? I have had my 2.8 iMac since last August and if I am not too far off, the last update before that was at least a year wasn't it? Maybe slightly less than that if there was a speed bump. I could see the mini getting something decent considering how far behind the times they are. Heck, if they lowered the prices back down to $499 and $599, I would get the current higher spec one for my wife in a heartbeat. It would be plenty for her needs, and a huge upgrade from her current (my old) G3 iBook. Seems strange to me that many people think there will be a brand new design for the iMac after only 8 months.
Just some thoughts.
