Just yesterday, Google announced its first foray into enterprise videoconferencing with the "Chromebox for meetings" set of hardware and software, based on the recently announced Asus Chromebox. Now HP has announced it's joining the Chrome OS videoconferencing wave this spring with its own Chromebox.
Asus announced a new PC running Google's Chrome OS, but it's not another Chromebook. The Asus's new Chromebox is an Apple Mac Mini-looking box running Google Chrome OS.
