Steve Ballmer sat for a spell with MIT Technology Review to discuss the Windows 8 ecosystem.

It’s no easy task to gauge the impact Windows 8 is having on the industry, in part because the industry is changing. The traditional desktop is taking a backseat in popularity to mobile form factors, like notebooks,tablets, and hybrids. Windows 8, as you know, is an attempt to bring all these devices together, along with smartphones, under a unified user interface. IsMicrosoft happy with its strategy up to this point?

Jason Pontin, MIT Technology Review’s Editor-in-Chief, had a chance to speak with Steve Ballmer about Windows 8 and related topics. One of the questions he asked is what Ballmer feels is a reasonable adoption period for a new version of an operating system that’s to be used by a billion people.

“Well, it’s a complex question. You’ll need to define what you mean by adoption rate. It’s affected by three things: How many do we sell? How quickly do people retire the installed base that they own? And what are the similarities and differences between the consumer market and the corporate market?,” Ballmer said. “In the first 10 weeks, we sold 60 million copies. All new consumer PCs are now Windows 8 based. So in that sense, I would say that here the adoption rate is perfect.”

Ballmer pointed out that consumers upgrade PCs less frequently than phones but upgrade them more frequently than TVs and game consoles. And in the corporate world, “adoption is always a little slower.”

And what of Microsoft’s Surface strategy?

“I’m super-glad we did Surface,” Ballmer said. “I think it is important — and not just for Microsoft, but for the entire Windows ecosystem — to see integrated hardware and software….Surface is a real business. In an environment in which there’s 350 million PCs sold, I don’t think Surface is going to dominate volume, but it’s a real business.”

The last time we saw Steve Ballmer star in a commercial for Microsoft, he was extolling the virtues of a 286-based PC running the glory that was Windows 1.0 -- in 1986. You can imagine the surprise we got 26 years later when Microsoft premiered an ad featuring the now-CEO during its Windows Phone 8 event. If you were expecting that same kind of unbridled enthusiasm Crazy Eddie once used to hawk underpriced TVs, you may be either pleased or disappointed. It's a very level-headed and well-spoken Ballmer this time around, with the executive calmly highlighting the advice he gets through his HTC Windows Phone 8X from people like his wife and a certain Billy G. Besides evoking nostalgia, the pitch is an illustration of what Windows Phone's live tiles can do as well as a reflection of Microsoft coming full circle -- as it was two decades ago, Redmond is fighting for market attention at a time when new interface concepts are challenging its main business. We're just glad there's fewer plaid business suits in 2012.
