I have ordered the Kogan Agora Netbook Pro, 10.2 inch. This is $569 delivered. It is essentially a colne of the MSI Wind (which Aldi also were selling). The Kogan has been configured with a larger 6 cell battery and 2 Gbytes of RAM (the Aldi unit had only a three cell battery and 1 gbyte RAM like most netbooks). The Agora has gOS Linux in place of Ms-Windows XP. This is a bit of a shot in the dark for me: my Twinhead laptop failed and I decided on a replacement in a hurry. Other netbooks I looked at were the Levono Ideapad s10e, Acer Aspire One, MSI Wind U100 and the Benq U101 (all of which are between $640 to $699).
One issue I have is the transition from Windows to Linux. Already I use Firefox and Open Office in place of IE and Microsoft Office. But I had not made the transition of my email from a very old Eudora and my accounting software is still on Windows.
Kogan have a very good e-commerce web site. But I needed telephone sales support (which was also good), because I could not find the button on the web to enter my credit card details. Using Firefox, the button at the bottom of the order form, where you enter your address details, was covered by a "comment" box. I found if I turned off styles, I could then see the button. Kogan need to make a change to the web form to fix this, as this netbook is likely to appeal to open source enthusiasts, who prefer Firefox to Internet Explorer. It would be a shame if the people the netbook appealed to couldn't order it.
ps: One advantage the Kogan Agora has it is only available in black (like a Model T Ford), other units are in a range of colours and often you can be stuck with a garish colour you did not want. My Tiwnhead laptop was white, which drew more attention to it that I wanted. In an extreme case someone in a Greek cafe saw me using it and rushed up to give a monologue about the value of computers in education (thinking the Twinhead was an OLPC).
