October sales figures obtained by the NPD Group suggest that Macs are up about 20 percent year-over-year, according to Piper Jaffray analyst Gene Munster. Based on trends, Munster forecasts that during the whole of the holiday season, Apple will sell between 4.1 and 4.3 million Macs. The impact of the new MacBook Air remains to be seen, he observes, since it was only launched in late October; November is nevertheless predicted to produce higher Mac units as a result.
