So, what's the story behind this Mozilla/Firefox vs. IE controversy?  For the home user, is it something to be taken seriously or is this more about politics/marketing and stealing thunder from Microsoft.

Dave seems to be strongly recommending people convert.  I know IE has a lot of weaknesses that are constantly being plugged.  Is Firefox really that much better or is it that with the smaller marketshare, hackers haven't yet exploited its weaknesses yet?
