Ive has to say that rectangles are clearly the superior form factor. It's his job. That doesn't mean that two years from now Apple won't have a round watch. It doesn't mean that they will, either.
EDIT: Also, uh, what if someone comes up with a really good use for smart-watches that isn't lists-related? "Dealing with lists" is not selling me on the need to buy another multi-hundred dollar gadget.
I guess we'll see over the next few years.
> Ive later tested watchbands by wearing them outside the studio with other watches. The shape of the body, meanwhile, barely changed: a rectangle with rounded corners. “When a huge part of the function is lists”—of names, or appointments—“a circle doesn’t make any sense,” Ive said.
