+1 on Chrome. I use it too.
BTW, what makes Mac more secure is that they are less juicy targets since there are fewer of them in the market place. They are installed in less critical locations, etc.
Rest assured, as Macs become more and more popular, they will become targets too. If Macs cross over to the "enterprise" in a big way you can bet on them becoming attacked just like their PC brethren. There is nothing inherent about the Mac's OS that makes it more secure. It is just less profitable to attempt to exploit them...
So for now, security through obscurity works....
