Ubuntu 11.04 version of is henceforth available for free download, according to Mashable.
This new version has a new Unity interface on top of its Linux underpinnings. Its most noticeable change is the application launcher on the left side of the screen. Similar to Windows 7′s taskbar, it lets drag and drop icons to and from it, as well as launch apps quickly and easily.
The Unity interface was originally conceived for smaller screens on netbooks, and offers easier file management, a new dashboard that gives you easier access to your applications and files, and Workspaces that simplify managing multiple windows.
This new version is reportedly working well with the cloud-based Ubuntu One service, letting users synchronize their preferences and files in the cloud.
A compelling aspect of Ubuntu is its customizability. One of my graphical customization tools for Ubuntu is Compiz, enabling wild graphical transitions between applications and window movements. Its best effects deal with 3D virtual desktops and windows that bend and wobble when you shake them.
The coolest characteristic of Ubuntu is that if users would like to try it, they can download its 698MB image, burn that to a CD, and then run it from the CD without having to install it on your machine. It’s a great way to try out this Linux-based operating system that’s getting to be so refined, it’s almost as easy to use as a Mac or PC.
