In announcing Apple's fourth-quarter earnings, Peter Oppenheimer, Apple's chief financial officer, said that the company had seen an "unprecedented demand" for its Mac line in the fourth quarter, selling 1.61 million Macs—the most ever in a single quarter.
The gap between PCs and Macs has been narrowing rapidly the past year, and is likely to continue to close. Given the near fanaticism that many Mac users have, Apple's biggest challenge is convincing PC users to “switch”. Their commercials and other propaganda, while often appearing condescending to many, seem to be working. More competition is always a good thing.
