In a meeting with financial analysts last week, Microsoft CEO Steve Ballmer laid out who he thinks are the biggest threats today to Windows on the client side. Surprisingly, Apple wasn't number one. It wasn't number two or three either.
Referring to a pie chart at the meeting that gauges threats to Windows, Ballmer said that Windows itself, both licensed and pirated, were the top two threats to Microsoft in the client OS space, followed by Linux, then Apple. Ballmer quipped: "Windows license, number one market share. Number two market share goes to Windows pirated, or unlicensed. That's a competitor that's tough to beat; they've got a good price and a heck of a product, but we're working on it."
