Recently Line2’s founder and CEO, Peter Sisson (News - Alert), posted a YouTube video explaining something of interest to mobile communications: “the new mobile desktop.”

He first whiteboarded the office environment familiar to a lot of people -- a desk phone, and desktop computer with CPU, you know the deal. Sisson noted that it might not be familiar to “some of the younger people watching this video,” noting “this is how your mom and dad works.”

Thanks Peter. Remind us to teepee your house next time we’re in town.

He explained that in the old setup, the phone’s attached to the wall with a cable, the phone receiver’s attached to the phone with a cord, the computer’s attached to the wall with a cable, everything’s quite... attached. And stationary.

Sisson said all that’s going away in favor of the mobile desktop, brandishing an iPhone (News - Alert) with apps “that let me do everything,” such as make calls, collaborate, access documents and share files. “This is my mobile desktop,” he said. He made the point that an iPad will do the same thing, and his MacBook Air will as well.

Yes, as Peter noted, iPhones and iPads and MacBooks combine the functions of telephone and computer and make it all highly portable. That’s why Steve Jobs (News - Alert) is a gazillionaire. The functionality is freed from static forms.

That’s what Line2 is all about, Sisson said -- enabling that kind of mobile communication. “We’ve got a lot of cool things coming,” he said.

Last month TMC’s (News - Alert) Stefanie Mosca wrote that according to a Pew Research report, an astounding 85 percent of Americans over the age of 18 own a cell phone today: “Needless to say, I don’t have to stress the importance cellular manufacturers, operators and carriers are faced with as the demand for mobile communications continues to grow.”
