You may remember Steve Ballmer (CEO of some other company) criticizing the iPod and iPhone on several occasions. Something that he definitely cannot criticize is the Mac, mostly because he was seen I guess Microsoft is staring to "Think Different," eh?
Update: As noted by several Flickr commenters, Ballmer didn't actually use the Mac to present; all that was displayed was his title slide, most likely driven by backstage gear, and presumably the MacBook Pro was left at the podium by the conference organizers or a previous presenter. Still a pleasant thought to imagine him slaving away over his PowerPoint (or Keynote!) presentation on the MBP, but it doesn't look like that's how it went.
This isn't specifically Mac news, but it is a name we all know well. Bill Gates has announced that he will be 
Microsoft CEO
Steve Ballmer is, let's say, a passionate guy. With Microsoft stagnating while the iTunes Music Store and Google (which
is practically synonymous with "search" these days) becoming the standard of what they do, he's got a lot of
stress to deal with. How does he manage? When he isn't sweating profusely, he's spending time with his kids...and
telling them not to use Google or iPods.
