It's been out overseas for some time, but it looks like the MSI Wind U120 has gone on sale in the US.
Unfortunately, the 10-inch Wind U120 isn't really much of an improvement over its predecessor. While the U120 has been upgraded with a fancy black matte screen, dissections have found the internals to be nearly identical to the U100, and the stat sheet agrees:
• Intel Atom 1.6 GHz Processor
• 512 KB L2 Cache, 533 MHz Bus speed
• 160 GB SATA Hard Drive, 1GB DDR2 667MHz RAM, 2 GB Max
• 6 Cell Battery
• Built-in Gigabit Ethernet LAN and Modem Module, Built-in 802.11b/g/n WLAN Card
The U120's claim to fame is 3G support (in the U120H), not found in the current model available at Amazon for $470. While this base U120 will surely come down in price, you might as well pick up a U100 for the time being and save yourself a $100 or so bucks, if you can handle the 3-cell battery found in the cheapest versions.
