Surprised to hear that apple doesn't necessarily have the highest priced product on the market or what?
When I last needed a dual socket machine, I bought a Mac Pro because it was pretty much the cheapest option I could find - including building my own white box system. I tried to live with the limitations of osx for a while too, but shudder at the thought of me running an apple branded machine without a single osx partition
I'd love for that to be the case again, but I'm not too hopeful - If they go for a single core i7/Xeon, it'll (carry on) being massively overpriced. Aesthetics etc couldn't be less interesting to me on a workstation, not sure why this is being mentioned. If I was loopy and was making my decision based on looks/build, I'd go with a nice solid steel caged machine, in black from hp/dell/supermicro/etc. One of the only features people might really need from 'a box' of components that are made by the same semiconductor firms is the ability to slide in a rack - apple love to keep their consumer product lines simple(ish), but they forgot to apply this to the Mac Pro when removing the Xserve! - I wish they'd rid the world of the atrocity that is osx server though!
And anyway, seems like a strange time to push a refresh (at intel's mercy...)
