The new Logitech AudioHub seems to be aimed more at the home user or business user that uses their laptop to play various types of multimedia. Since most speakers that are found on laptop computers are tinny and shallow sounding, Logitech went to lengths to try to cram high quality sound rendering into a fairly compact package. The reviews seem to say that the audio quality coming from the two diminutive black speakers is acceptable, and for the most part worth the $100.00 investment.
On the down side it's kind of ugly, but that's just my own personal opinion.
Along with the upgrade in audio quality, the Logitech AudioHub also sports a built in three port USB hub, integrated subwoofer, and a removable web cam stand. The two speakers are adjustable to fit almost any notebook PC. No shipping date was given in the official Logitech press release, but expect it to be available in the fall of 2007.
