Why is everyone saying BackTrack is outdated? It's based off an LTS version of Ubuntu and is still completely supported: https://wiki.ubuntu.com/LTS
it's based off of 10.04 (lucid) which while in theory is still LTS but does not get nearly as much attention as other releases and BT uses different repos then normal lucid for most of it's programs which have out dated versions (with the exception of firefox and a few others) and they slapped on a kernel version that is no where near what lucid was designed to work with.
