The Asus eeeeeeeeeeeeeepc is a wonderful machine. The boys took it to Europe, and used it constantly in wifi spots, such as bigmacland. But the default operating system is a bit of a dog, and is disowned by Xandros, and Asus doesn't know English too well.
So, it is inevitable, that if you continue to do updates, you will fill the teeny disk, and bugger the whole system. What to do?
Well, install Xubuntu, which works great, and has less security holes.
