Dell Latitude 2100 seems to be more like a low-cost business laptop than a netbook. Moreover, for linux option, that is a standard Ubuntu 8.1 rather than a Ubuntu Remix.It doesn't sounds very "Notebook". But it got notebook features. Light-weight! It is only 1.3kg. Moreover, the color options are available as well.

I am thinking that is a better option for myself than Dell-mini. Becuase it may has RAM up to 2GB and Harddisk to 250GB. Moreover,it got a touch screen option(But it costs AUD$101 more, I won't go for this). This sounds attractive!
