"Well, there's always...
Opera"
As I understand it, Opera uses IE's engine, it's got all the vulnerability of IE. Not that it's not a nice browser, but it's no more secure than Firefox and most likely a lot less.

That's false. Unlike many "alternative" browsers, Opera has it's own engine. And, for whatever reasons, Opera's current and past versions have consistently had fewer UNPATCHED security problems than IE and Firefox.
