After much deliberation I ordered a MacPro 2.66 X1900XT airport, then just as the documentation email arrives outlining my right to cancel within 10 days I'm reminded of the futility of keeping up re: Clovertown announcements. "AAArgh!" my wife exclaims just buy the damn thing already! It's nice to move at the right time get gd value, and that's what tempts me to hold off...but it could be for nothing if come Jan/Feb all that's added is top-line Clovertown and minor price adjustment to Woodcrest. Also mindful of $ needed for RAM & HD in MP. 8-core might be a compromise if all I can afford is the 1.86 Ghz due to lack multi-threading software. I'm buying primarily for: FCS 5.1 (esp. Compressor speed), Aperture, Nikon CaptureNX. Utterly indecisive, and obviously it is more a want than need otherwise I wouldn't have the luxury waiting, but with the G5 gone it will be frustrating wait back to the G4 DP500 as stop-gap.
