Open Office all the way for me... I'm an open-source fanatic. Yes, one of
those people
I can boot Linux off of my USB drive which is integrated with my watch, so on school computers I can stick my watch in the computer and run Linux/Open Office without having to install anything. Plus, then all of the restrictions the administration put on the computers no longer apply to me, since they haven't figured out how to put a password on the BIOS (once they do, I'm out of business)
Hooray for uber-geekery.
