As per my experience, Ubuntu/Linux has been the most light and fastest operating system so far for desktops or laptops. There are millions of users around the world who love to work on Ubuntu only. Good news is Ubuntu is now also available for Android portable devices with full desktop experience. You can download fully customized Ubuntu 10.10 image themed and optimized for mobile and tablets running on Android.
You can also install this Ubuntu without removing original Android OS from your Tab or Smsartphone. Yes, thats correct. You can install it along side your existing Android install.
