Anyone who reads the fine site Book of Joe knows that the man behind the blogging empire is religiously devoted to working out while writing, and prides himself on having integrated a treadmill into his workspace. Well manufacturer Steelcase thinks that this trend has grown beyond one individual multitasking in his underwear, and is poised to introduce a nicely-designed product called the Walkstation which seems more at home in a CEO's office than your messy living room. Not many details are available on this converged piece of furniture co-designed by the Mayo Clinic's Dr. James Levine (who's been working in this specialized field for at least two years, apparently), but supposedly there's an all day demo going down on October 25th at 4 Columbus Circle if you happen to be in the New York area. And if you do go, try to show up in a cab just to be ironic.

Update: We've learned -- unsurprisingly, from the Joe mentioned above -- that this rig will retail for a cool $6,500, thereby making it the Rolls Royce of integrated workstations. Thanks, Joe, and keep, um, running for the stars!

Update 2: Whoops, guess there's no demo going on after all. You can still show up to that address, we guess, but you certainly won't have the good time you would have had working and exercising simultaneously.

Everyone's got their own idea about how we're gonna get our work done in the future, and except for the camp that envisions us toiling away in the silicon mines for our robotic overlords, most of these concepts seem to have converged around a few of the same elements. Well Microsoft was showing off its Center for Information Work's take on the ideal workstation at Convergence 07, and the so-called DigiDesk does indeed incorporate many features we've seen before, including a multi-touch display (we know, we know), document digitizer, speech recognition engine, and ability to resize objects on the fly a la Jeff Han's famous TED presentation. Of course Redmond conveniently neglected to tell us when we can expect to to find the DigiDesk at our local Office Depot, meaning that like most of these neat-o concepts, a YouTube vid (after the break) is probably the closest you're gonna get to this tech for a long time.
