Hello guys i use bt, for some while about a year, just for curiosity. I have a simples question, backtrack is just and ONLY, for security testing or i can also be used for standard use, same as Ubuntu, Debian, etc?

I wanted to replace ubuntu for backtrack, but i also want to be available to do the same things i used to do in ubuntu (normal stuff)... I think i can be done.
But i want to know what you think!
