What's wrong with having a 5% market share? Safari is good, and so is Opera. Both are great when it comes to compliance to standards (Somebody correct me if I'm mistaken), and are pushing the envelope as much as the three big players. Also, Safari (or, like, 99% of it?? Somebody also correct me if I'm wrong) is open source in the form of WebKit. I don't get this mindset that says that everything now needs to be a monopoly or duopoly. Why can't small players participate too? What happened with choice?
