If that’s more money than you’re willing to spend, you can always pick up a refurbished Eee PC 701 for less than half the price. Or you can pre-order a CTL 2Go PC (Classmate 2) from Amazon. The Classmate featrues a 9 inch 800 x 480 pixel display, and a 40GB hard drive. The Windows version goes for $469, while you can get a Linux model for $399.
Update: The Eee PC 900 is now officially available.
