This might just be the netbook we've been waiting for: An Nvidia Ion-powered HP Mini with an 11-inch, 1366x768 display for 400 bucks. And you can actually buy it soon! September 23. Did I mention it plays 1080p video awesomely?
It ships with Windows XP initially, though if you can wait til October, you can buy a Windows 7 model for $475—by comparison, the original "first" Ion netbook, Lenovo's S12, is completely unavailable until October, and will be $550, with a lower res (1280x800) screen to boot.
