Hello,
I installed Debian Lenny on the Acer Aspire One.Lenny is ideally suited for netbooks as it has a lighter foot print with good looks. A week ago I had already installed Lenny on my pen drive for testing. Lenny DVD has a superb boot menu that lets you choose your desktop without having to remember the exact syntax. (A minor error in the older method meant that instead of KDE, you end up with Gnome. I had selected KDE. Those who do not like KDE4.1 will love this older KDE. Lenny comes in a down to earth build yet good hardware support.
Everything worked fine except wireless and thats where this site comes in handy. I used the mad-wifi drivers using the apptitude method given in the link. That is the fastest.

After that the system was restarted and Knetworkmanager was able to get me online. Gnome users please read about network-manager not working and instead the use of wicd.
Otherwise everything isthe same as setting up Kubuntu in Acer Aspire One.
