Typically CEO’s don’t have time to go out and make sales calls but for Steve Ballmer, Microsoft’s outgoing CEO things are a bit different.

It’s undeniable that Microsoft isn’t the giant that they used to be in the nineties, but don’t misinterpret that to think they are at deaths door. So why was Ballmer, out hawking Microsoft to hot mobile company FlipBoard?

Probably because no one has been a bigger cheerleader for the company since Ballmer. If you’ve ever seen the movie Pirates of Siliocn Valley, it was Ballmer who was the mouthpiece, the sales guy, during the earliest days of Microsoft and as he prepares to leave the day to day operations of the company he helped build and loves, he’s back at it.

Flipboard CEO Mike McCue told Business Insider that they had built a version of the popular news reading (and now e-commerce) app for WIndows 8. That was surprising because Windows 8 isn’t a priority OS for most developers, in fact it took three years for Instagram to make it to Windows Phone.

McCue proceeded to tell Business Insider’s Jay Yarrow, that part of the reason they chose to develop Flipboard for Windows 8 was the fact that Steve Ballmer himself came to their offices to pitch Windows 8 and the Surface tablet, complete with pre-release tablets in tow.  McCue told Yarrow that he found Ballmer’s “enthusiasm for the product” to be inspiring.

Ballmer has been doing an exit tour of sorts, and saying a lot of goodbyes, but when he does he still has the same fire that he’s had throughout his career. While finding a good CEO to guide Microsoft may be a challenge, finding a bigger cheerleader than Steve Ballmer is going to be nearly impossible.
