How good is the Qubes OS, and what makes it different from existing OSs?
I've been hearing chatter about Qubes OS, but to be honest I know almost nothing about it. Initially, I thought it was "just" another Linux distribution, but apparently it isn't, although it uses Linux drivers and runs Linux applications. The developers' apparent focus on security through virtualization is welcome and an interesting architecture choice, but I wonder how Qubes actually works as an OS, and if it is noticably different from other OSs in function. Is it worthy of giving a trial, or is it more of a novelty OS?
