tried it...while i liked the speed, i didn't like how there weren't that many options. for instance, you couldn't keep your browser in incognito mode every time you opened it; you have to go into the page menu and select it. you also have to delete your history everyday; you can't set the save history time to zero like you can with IE. i like to view a lot of porn, but i don't like to leave a trail of the sites i've gone to as it could get me in trouble with the wifey

also, the website i use for work has a pop up that opens in another window as opposed to opening a tab, which can be annoying because if i click a link on the pop up, it opens a tab in the first window (hope that makes sense). oh and i'm still using IE6...IE7 slowed my comp to a crawl.
EDIT: i also have a scroll feature on my touchpad mouse, but with Chrome, it scrolls all the way up or all the way down...it doesn't stop anywhere in the middle. my back/forward feature on the mouth doesn't work with Chrome either.
