For the conversation above, I can see that most of use guy/gal use linux just because it is free and only for learning purposes.

Why would someone use Ubuntu? It is slowest among all Linux distro, the only good thing is it is simple to install simple to update and simple to use and also it come with all the require "packages" the we usually use. Credits? it really have everything a normal user need. Even my girlfriend can used it without any problem. Chatting, browsing, watching movie, and do office document reporting, and etc. Wonderful.

Red Hat/Fedora/Suse/Mandriva? if You have install and uses it, you should know it take up almost 8 GB. I think it is ridiculous to install every packages into your computer. Do you know that how many daemon process is running when your Red Hat/Fedora/Suse is running? There is at least 30 daemon processes you don't need it to be running, and at least 50 application that you don't need is installed in your machine when you select all application during installation.

The reason for me to use Linux is because it is fast and extremely configurable, thus i opt to use Gentoo Linux. Why Gentoo, because it is the closest distro to LFS. You have to select packages and compile it on your machine. Thus you can compile it according to your own need. It is like buying a tailor made shirt. But the installation might take up 3 hours if your internet connection is 1mB/s, and you are using a decent machine.
