Canonical doesn’t plan to launch Ubuntu Netbook Remix for a few more months. But if you’re itching to check out the customized version of Ubuntu designed for low cost subnotebooks like the Eee PC, the current source packages are already available for download. Keep in mind, this software is still under development, so your results may vary. Of course, open source software is always under development, but if you don’t want to risk mucking up your Ubuntu system, you might want to create a new user to test out the Netbook Remix interface.
The switcher bar is basically just an applet that you can add to the Gnome Panel. Underneath all the shiny Netbook Remix lies a full version of Ubuntu. So if you like the program launcher but not the switcher bar, all you have to do is remove the panel and customize your screen to your heart’s content.
Aside from the visual changes, Netbook Remix will also be optimized to work with Intel’s low-power Atom CPU. While this doesn’t necessarily mean that a stock Ubuntu distro won’t work with an Atom chip out of the box, Ubuntu Netbook Remix will be designed to take advantage of the chip’s power saving features.
