This thread went a bit off topic. Here is some info on the Acer Aspire One - known as AA1.

If you do a bit of reading you will find out that many of these netbooks are quite poorly supported still in standard Linux distributions, unless it's just a laptop thing. Many have wifi, audio and webcam driver issues. Most of these can be worked around and if you decide to install a full blown Linux distro then there is a lot of info out there. I have been finding about my Samsung NC10 which I intend dual booting with windows XP and some flavour of Linux, probably Ubuntu as there appears to be most support for the NC10's at the moment. I can not manage without windows so it will have to stay.
