Hey!
Okay, that's a fair call.
Oh, I forgot to mention that Activity Monitor will show you My Processes by default (processes owned by the user) but there's a drop down list from which you can change it to All Processes.
Also, although you can force quit apps from Activity Monitor's processes page, a quicker way to force a frozen app to quit can be reached through COMMAND-OPTION-ESCAPE where COMMAND is the button with a little Apple logo thingy on it.
