Well I finally took delivery of a shiny new MacPro quad core Xeon.
I have to say it was a decision made for me by the continuing requirements of current software.
When the new iMovie failed to load that was the straw that broke the camels back.
I put if off for long enough but the wait was worth it.
I can stop bugging Petrina for Aperture and Joost and the Mac Pro runs HD video a lot better.
