How many web browsers do you have on your computer?

(no, it's not my desktop)

Simple question: how many browsers do I have?

I use Opera for reading reddit and browsing, Webkit for gmail and google docs (it's really fast), Firefox for web developing (FireBug rules).
I use virtual machines, so it's not so easy to count :)

• main operating system: opera, firefox, safari, webkit
• secondary os: opera, firefox, safari(comes with itunes), webkit, internet explorer 7
• 1st virtual machine: konqueror, opera, firefox (i'm not counting links, lynx, elinks...)
• 2nd virtual machine: opera, firefox, internet explorer 6

... it's only 15 browsers on one computer. Of course most of them aren't used very often.
