Tails (The amnesic incognito live system) is a live OS based on Debian GNU/Linux which aims at preserving the user's privacy and anonymity by using the Internet anonymously and circumventing censorship. Installed on a USB device, it is configured to leave no trace on the computer you are using unless asked explicitly.
As of today, the people the most needy for digital security are not computer experts. Being able to get started easily with a new tool is critical to its adoption, and even more in high-risk and stressful environments. That's why we wanted to make it faster, simpler, and more secure to install Tails for new users.
On a related note, Tails 2.0.1 was released a few days ago as well.
