Opera 10.5 beta is so awesome, I have to advertise
Most secure and fastest, and the latter I can guarantee.
I was amazed by it, and Opera used to be really fast already...so it's something to consider xD
Faster and more secure than Firefox, Chrome, Safari, and of course Internet Explorer, which is the worst in everything
Lol I sound like I'm paid by them. No, Opera is just awesome like that.
