Or a surf-by web infection (NoScript can help; NoScript is also a pain)? Or a flash bug? Or any other exploit an attacker will try to use (and the metasploit framework, among others, makes it trivial to set up these) that doesn't require a root exploit to drop stuff in your .bashrc?

PDF fill-in forms are required in many cases as well. When one of those are compromised (not if, when), how will standard user-based protections help you in a way that doesn't require highly inconvenient solutions like switching users or running 'dangerous' apps in a VM?
