My first impression was that the design is for left handed people, but then again, it’s been years using windows and having the window open/max/close controls on the right side of the screen doesn’t feel natural to have them on the left, this is just a feeling thing though.
UBUNTU still needs some year of development but the main features are already working and are very sleek and functional.
I really liked the idea of having an Application centre just like App Store from Apple, it works fine for people who wants to customize their computer without further effort, then again the native browser is Mozilla and you can also install Google Chrome (Chromiun) it’s good news for the freeware enthusiasts.
Installation process is very easy and guided-through. If you are curently using Windows you can give it a try by using some partition on your hard drive and install Ubuntu without affecting your Windows settings.
Here you can find the link if you feel like experimenting a little with your computer and install a free Linux OS: http://www.ubuntu.com
Good Luck!
