Not to be contrary or anything, but what you define as better is very subjective. I would not consider open office superior to MS office in any way. The only benefit it has is its free which doesn't concern me since my office pays for the software anyway.
Also, I'm not all that confident that linux and FF are any more secure than XP and IE7. It's possible they are, but until you have a similar install ratio to temp hackers and malware writers, I don't think you can claim anything definite.
PS, I hate FF. Man I can't stand that browser. Also, I run XP (fully patched at all times), no virus protection and a simple firewall, and I've never gotten a virus or anything worse than some tracking cookie malware, ever. It's pretty simple to keep clean by practicing smart computing.
