Broke down and bought one of the new DP 1.25 PM's with the 20" Cinema display. I've had a 15" FP iMac for a while (pretty much switched completely from the Windows world), and was considering getting a speedbumped 17" in the next few weeks (assuming they are actually released). However, the new prices of the Cinema displays along with supposedly quieter PM's with Airport Extreme kicked me over the edge. I'm impressed - while I'm sure a 3GHz Intel box may be faster on many things, this thing really flies. I even thought about holding out for 970-based PM's, but decided that this would be a useful & satisfying machine for a couple years. OS X is very responsive on this thing, even iMovie3 is pretty good (it was unuseable on my 700 Mhz iMac). I've currently got 768MB, but I'm going to order another 512MB DIMM next week. Probably get a Pioneer A105 too (iDVD3 is installed on the hard drive, even though the new 1.25 is a combo drive machine). The new 20" Cinema is fantastic, BTW.
