Engadget found information about the upcoming Dell Inspiron zinoHD system. There seems to be a nettop version and a more powerful AMD Athlon based version:
The Inspiron 300 has more of a nettop slant, with an Atom processor and integrated graphics, and though it has a DVD burner and 3.5-inch HDD, there won't be HDMI or eSATA ports. Meanwhile, the Inspiron 400 can handle an Athlon or Athlon X2 processor, with an option for ATI Mobility Radeon HD 4330 discrete graphics (not quite a "desktop" part, if you ask us) and all the other goodies like a Blu-ray option, HDMI, gigabit Ethernet, dual eSATA and so forth. Interestingly, the manual also mentions XP, Vista, Windows 7 and Ubuntu as supported options -- though we're not sure they'll all be available as retail configurations.
