The Pine Trail netbooks from Lenovo were outted last month, and now the Lenovo S10-3t 10.1-inch netbook is available for pre-order on Amazon for $499.99. One downside is that it ships with Windows 7 Starter edition, so that means limited software, but you can always upgrade.
The S10-3t netbook features a screen that can be swiveled 180 degrees, which is pretty convenient if you like working at odd angles. It also has a NaturalTouch Panel. Is this the netbook for you?
