Apple is likely working on a standalone, Internet-ready TV that could ship in the next two to four years, says Piper Jaffray analyst Gene Munster. While similar claims have been made for some time, Munster cites several signs that Apple has a project going. Among these is the new Mac mini, the first to include HDMI output. The computer is popular as a media center system, and Munster argues that Apple intends to push the Mac further in this direction.
