Intel Moblin 2.0 has been released recently. A lot of OEM vendors will be shipping products based on Moblin v2.0 for Netbooks, so if you are a Linux user and surveying which one Netbook will fulfill your requirement, you can wait for Netbook based on it to be ship although a lot of Netbooks have being sold in the retail market.
Moblin is just an Intel distribution of Linux (based on Fedora), although it's one that benefits from some unique tweaks and a newly designed user-interface. Moblin is based on the familiar GNOME/GTK desktop, like distros such as Ubuntu, but this is largely invisible because of the UI improvements.
