Every April, Canonical releases a new version of the consumer-oriented and very popular Linux distro Ubuntu.
The latest version is called Ubuntu 11.04 Natty Narwhal, and the biggest change in ths version is a completely new user interface called Unity. Unity is an interface that that was previously reserved for netbooks.
Aimed at developers, Bash brings a complete Linux command line to Windows, but only the command line.
Yes, that is correct, as per industry sources, Canonical - the company behind the popular Ubuntu Linux distribution and Microsoft have partnered up to integrate Ubuntu into Windows 10.
It's not a Linux distribution, but it's practically a new Ubuntu flavor.
