Even though we're in the middle of iPhone madness, Apple has some good news coming out of its Mac department: market share went up last month.
According to NPD, Mac market share increased from 11.6 percent of the market in April to 13 percent of the market in May. Note that NPD tracks only the U.S. retail industry; those numbers include PC sales at places like Best Buy and Circuit City, but they don't include direct sales, meaning that Dell's totals are excluded.
Still, better to be going up than going down. Apple's notebook share is now 14.3 percent, up from 12.5 percent of the market in April. Desktop share was only up a fraction, to 10.4 percent from 10.2 percent in April. Apple trotted out new MacBooks in May and new MacBook Pros in June just ahead of the third-quarter back-to-school shopping season, traditionally one of the company's strongest.
