As I pointed out elsewhere, today's Macs will run Windows just fine, particularly in a VM.
This is a great solution as you move from legacy software to something better. With so much business software being done as web applications now, the target machine and OS are becoming less important than the supported browser. Bill Gates rightly feared the browser software platform, and Windows is certainly being marginalized due to it.
We'll see if Apple starts to set it's sights more in the direction of "the enterprise". As most highly capitalized company on the stock exchange, it can certainly afford to do so.
Sorry. FR needs an "edit" function.
