I use Maxthon for almost everything (the fastest browser in the world) It's not the most known browser in the world but I did my research on browsers and tryed loads and that one turned out to be just perfect.
I use google chrome on my netbook, simple fact is it came installed and all i use it for is the internet.
On the main computer I also have firefox for facebook games due to greasemonkey/userscripts. then Ie as its there if its needed
