You can download it from here:http://www.ubuntu.com/testing/maverick/beta. Choose the netbook edition. Create a Live CD using the Ubuntu Startup Disk Creator or Unetbootin onto a 1 GB USB thumbdrive or SD card. Restart your computer then run the Live CD to install the new Ubuntu 10.10.
If you have the Ubuntu 10.04 ( Lucid Lynx ) installed then all you have to do is press alt+F2 then type ¨update-manager -d¨ without the quotes then press run. Update Manager will appear and tell you ¨New Distribution Release 10.10 is available, just click upgrade and follow the on-screen instructions. By the way you need to have 1.2 GB free on your hard drive to be able to upgrade.
Install the following after you run the Update Manager:
VLC : for playing all kinds of videos and music
UBUNTU RESTRICTED EXTRAS : for Java, Flash Plugin, Microsoft Fonts, other codecs, etc.
UBUNTU TWEAK : tweaking the system
GOOGLE CHROME/CHROMIUM : as an alternate browser
Tested it with my own Asus EEEPC 4G. It works out of the box.
But if you´re afraid of encountering bugs then you should just stick with your current system.
