Looks like the MSI Wind is available for pre-order in the US. The 8.9-inch Intel Atom-powered mini-notebook has definitely been generating a lot of interest recently.
There are two models, the U100-Windows and the U100-Linux. One big difference, at least for now, the Linux version appears to come with a 3-cell battery while the Windows has a 6-cell battery (up to 6 hours of battery life). This should change in the future as more options become available (and/or 3rd party batteries).
