"Tails takes the form of a bootable live image that can be used
from a CD ROM, a USB stick or via a network boot. Once booted, it
executes from RAM, taking care not to make use of a swap partition.
The desktop is Gnome 2.0 and the applications are a fairly standard
selection. The web browser is an old, but usable, version of
Iceweasel 3.5 (Debian Firefox).
There are other applications to handle graphics work, audio
editing, media playback, text editing, instant messaging and a
email client - basically, everything you need when you're on the
run from enemy agents. Extra software can be added via the Synaptic
package manager which pulls directly from the Debian repositories.
So far, so similar to most other live desktop distros. Security and
limited footprint on the the host machine are the areas in which
the distro differs from the run of the mill.
