We already mentioned ThinkSecret's post about a Mac mini-based home media hub, and it's also speculating on the content delivery system that device will use. AppleInsider is claiming that the company will expand further into consumer electronics from its iPod division, including an iPod-powered boom box.
In the labs, we value cold hard science over anonymous "insider" information, but we're not going to let that stop us from speculating on how much of this stuff is likely.
