iPhones, Macs gaining among business users

jbrodkin writes: "The focus at this week's MacWorld expo is on consumer technology, but Apple devices are quietly making gains with business users as well. Corporate usage of Mac desktops has quadrupled in the past two years, while 50% of businesses are increasing support for the iPhone, recent surveys show. Industry observers say Apple lacks a broad strategy for penetrating the business market but is making gains despite itself."
