i use safari.
its bundled with my OS, but doesnt actually suck, like IE.
it doesnt use 300 mb of ram like frefox does.
with no add-ons installed and just opening the browser up it uses like 20% of my ram.
and i had bad experiences with chrome when it was first released (there were like no plugins that worked for it, like flash player or java)
and netflix doesnt work with chrome.
