Hmm. I will surely try it. Which version should I download 14.04.2 or 14.10? Is it easy to use??
If you want a Linux distro (Operating System) based on Ubuntu, let me recommend Xubuntu. Choose a KISS distro
(Keep It Easy, Stupid), ie a distro for Linux beginners.
For me, the best to begin are:
Zorin (aesthetically very similar to Windows 7, based on Ubuntu),
Q4OS (aesthetically, a clone of Windows XP, based on Debian Stable), the afore mentioned
Xubuntu 14.04 LTS and
Manjaro Xfce (very intuitive both, Manjaro is based on Arch)
Download a live CD / DVD. You can burn it to a CD/DVD or USB and test it without installing anything on your computer. For a better idea, you can always install it on a virtual machine.
Linux has many distributions with different desktops, you will find the most comfortable for you.
Do not forget that you can run Chrome, Firefox, Opera, Thunderbird, qBittorrent, Amule (emule), Libreoffice ... worth trying it
