A nice read with views on Apple's Intel the value offered by the Intel based Macs.  A powerful quote from the article:

"Apple now has personal computing platform that is comparable in cost to most of its competitors but is more functional, more inherently secure, has more plug and play features and, incredibly, more open. All the disadvantages that kept PC users away from the Macs of the past are gone. Both platforms share the same hardware and users can even share data between Mac and Windows applications running in different virtual Windows."
