Absolutely Free Fully updated version High security More tools for web masters and Networking Open source technology Easy to use Flexible for Laptop, Desktop and servers Every six months we get the newest version First of all you try to install it on your machine. Don't worry it's not a difficult thing. You can use a virtual machine to install it on your current OS. I use sun virtual box . So you don't need to reconfigure your had disk. After your installation, you need to know about few commands and tips in Ubuntu. I prefer following sites to gain your knowledge in Ubuntu.
