Apple is making small inroads in the professional market with its critically acclaimed line of Mac desktop and laptop computers, and even slight market-share gains can bring meaningful new business to the company.

Apple's share of total new PC shipments in the U.S. jumped to 5.4% last year from 4.5% the prior year, Gartner says. Nearly all of the rest of the market is Windows.

Apple Chief Executive Steve Jobs this year said the company's research showed more than half of all people buying Macs were new to Apple computers.
