A fundamental reason behind the commercial success of Windows PCs over Apple's Mac has been the wide price gap between the two platforms. Apple computers always cost more than PCs, so most people save money by buying into Windows.

Right? Wrong. Today's Macs are often cheaper than their Dell equivalents. And the new Mac Pro is ridiculously cheaper than the Dell Precision 690 workstation.

I configured a Dell Precision 690 to match the tech specs of Apple's base Mac Pro. In fact, I even paid to add more RAM to the Mac to exactly match the Dell.

And the saving was still £2,046! Enough for me to add a second DVD-R drive and Apple's iLife suite of creative apps, and still be less than half price.

Dell Precision 690, dual Xeon 2.66GHz, 2GB RAM, 250GB hard drive, 256MB nVidia graphics: £3,975 (inc. VAT)

Apple Mac Pro, dual Xeon 2.66GHz, 2GB RAM, 250GB hard drive, 256MB nVidia graphics: £1,929 (inc. VAT)

Whether Apple focuses any marketing on this amazing turn around remains to be seen, but this switch in expenditure is truly astounding.
