"Windows is now so big and onerous because of the size of its code base, the size of its ecosystem and its insistence on compatibility with the legacy hardware and software, that it just slows everything down," observed David B. Yoffie, a professor at the Harvard Business School. "That's why a company like Apple has such an easier time of innovation."

Actually, until the advent of the new Intel Macs, most applications since 1984 still worked fine on the latest Apple machines. This may have something to do with "well conceived and thought out hardware and software architecture" versus the "quick and dirty stuff duct-taped together" that drove Microsoft developments for some years :) Fortunately, perl's kin is obviously not from the "quick and dirty" breed.
