We already knew most of the details on the MSI Wind, but the Atom-based ultraportable just got official US pricing and availability today -- and just like we hoped, it got a little cheaper on the trip over. Although there'll be both 8.9-inch and 10-inch versions worldwide, we're only getting the 10-inch in both XP and Linux flavors, starting June 3rd. The SuSE version will feature that 1.6GHz Atom, 512MB of RAM, 80GB hard drive, and a 3-cell battery rated at 2.5 hours of use for $399, while the XP edition will come in at $549 with 1GB of RAM, Bluetooth, and a larger 6-cell battery good for 5.5 hours. There's also apparently going to be a $500 "base" XP edition, but details on that are pretty sparse at the moment. Looks like ASUS had better get that Atom-based Eee 900 out by June as planned if it wants to keep up, eh?
