Ballmer urges troops to slap down Apple and Google
Later in the memo, he wrote "In the competition between PCs and Macs, we outsell Apple 30-to-1" but admitted Microsoft's position vis-a-vis Google is not as strong as it is on the desktop: "We continue to compete with Google on two fronts - in the enterprise, where we lead; and in search, where we trail."
It would probably be more accurate to frame that as "PCs preloaded with Windows outsell Macintoshes by 30-to-1" - as far as I know, Microsoft doesn't sell PCs apart from those Surface tabletop jobs.
Both Gartner and IDC give Apple around 8 percent of US PC shipments, which means the ratio is at worst (from Apple's perspective) 11.5-to-1 in the companys' home markets.
It's probably about right globally, though. IDC says Apple has 3.3 percent of the worldwide market, which is roughly 30-to-1 if you assume that every PC shipped with either Windows or Mac OS X. Linux has got to be in there somewhere, especially with the apparently growing interest in UMPCs such as Asus's Eee range.
Ballmer clearly doesn't underestimate Apple - read on to see how he plans to compete with Cupertino.
