Most of the bitching we do doesn't apply in Windows.
Really? I
was actually talking about the machine, regardless of the OS it's running - although you could argue that it's even less stable in Windows. The only Vista BSOD's I've seen (from a partially non-BC, 'proper' driver install) for more than 12 months are from the Pros and other Apple hardware (via BC).
As I said, you get what you pay for - the Pro may be cheaper than a similarly configured Dell Precision T7400 for example, but they won't be usable (nor supported - by cheaper, did you include the cost of the inclusive Dell NBD support, let alone the 24/7 4-hour response paid-for uplift in your comparisons?) in the same way -
especially in Windows.
EDIT: Actually strictly speaking I tell a lie - I have seen BSOD's on another machine - Vaio TT, which was replaced. The numbers of Pros I have, the number of them we tried BC/DB on, and the number of instabilities encountered would seem to exclude a faulty machine.
It's a very pretty and neat/tidy and comparatively marginally more quiet (at idle) machine inside but that's not necessarily what you want out of the dual-Xeon workstation, unless your needs are so inconsequential as to place those priorities over more actually important attributes like stability, real-world expansion potential, business-critical support, etc. I've said before and I'll say it again - they're high-power home computers in concept and execution. If that's what you want, then great.
