I have a AOA110 with 1gb of RAM. I manage to install Windows 7 on an external drive and boot from it. (Thanks to Google) Speed is good, but definitelly would need more RAM, will probably upgrade to 1.5 when the waranty is over. I installed AVG but disable email scanner. I disable also Windows Defender. What else can I disable, to gain more free RAM? With XP I have about 75% free RAM. While with Windows 7, it is arround 50%. The only problem I found was with the Wireless card, it some time does not detect the card, (reboot solve the problem most of the time.) Cheers, HVL
