Apple CEO Tim Cook may have hinted at the prospect of an Apple TV set during today's now-concluded talk in front of the Goldman Sachs Technology and Internet Conference. The executive was asked about the current Apple TV set-top and possibilities such as a full-sized TV. "We don't want to send a message to you or shareholders that the market for it [the Apple TV set-top] is the size of our other businesseswe don't want to send a message that the length of that leg on the stool is the same as the others," he commented.
