I also have an Acer Aspire One w/160gb. Left XP but loaded Easy Peasy - Ubuntu.
It works fairly good. One of the big things is when an app is expanded all out
you do not have direct access to the expand/collaps/kill buttons in the upper
right hand corner of the screen. Under System/Preferences/Windows/Movement Key I
have checked the SUPER (Windows Logo) key. Now when I hold down that key and
click on a window it collapeses to about one-half size. Then it can be moved,
resized or quit.

There are a few problems and the 9.04 version didn't correct them. I may remove
Easy Peasy and go with the straight 9.04 version. Indipendance Day weekend I'm
going to my son's house in Atlanta. He knows much more about Linux and such and
has ask me specifically to bring the AAO because he has not seen one. That
weekend lots of changes will be made to it. These netbooks are nice but the
supporting software have not caught up with them.
