we have 7 windows machines here and we just bought a couple of Macs:
a Mac Pro 2.8 GHz Two Quad Xenon/2x1GB/320GB/SD with an Apple Cinema HD Display 23' LCD ... and a MacBook Pro LapTop ... I just unpacked them and set them up and I am looking forward to playing with them .... we will be adding another 5 Macs and keeping the 7 windows based PCs making a total of 14 ... balance is everything!
the next Mac we will buy will be the 8-core Quad Xeon 3 GHz whch is a 32-core beast!! $6427 is the cost of the tower in Australia but after seeing what it can do, it's well worth it!!
