When I'm running, topless, in my high-rise New York apartment, I often wonder: what are my friends doing? Are they on a treadmill right now? And if they are, why don't we just run together, properly, outdoors? I joke of course. Outside is dangerous. Cars. Pollution. Other people in general. Fortunately, Nautilus' T618 Treadmill will let you (kind of) run with buddies and online strangers, courtesy of tech from RunSocial. It'll also display a view of one of several beautiful outdoor tracks, with the scenery going past as fast as you're willing to run.
