The Acer Aspire One Laptop comes with a choice of Windows XP or Linpus Linux Lite. The custom Linux distro is designed to be easy to use and resembles the Xandros Linux “easy mode” software that Asus ships with some Eee PC models. But while the software makes it easy to find and launch applications with minimal effort, it’s a bit trickier to download and install new applications.
Enter Linux4one. This custom Linux distribution is based on Ubuntu, but it’s tweaked to support the Acer Aspire One’s hardware. Linux4one also uses the Ubuntu Netbook Remix interface which, like Linpus Linux Lite, provides you with large icons for frequently used programs and separate tabs for categories like Internet, Administration, and Favorites. Best of all, since Linux4one is based on the popular Ubuntu Linux operating system, there are thousands of open source applications that will run on the OS.
