I downloaded it yesterday and have been using it ever since; I think its pretty awesome. Quick, lightweight, and everything managed within one window. I love the separate task manager for tabs too, so you can see exactly which sites are using your resources. I haven't used Incognito mode yet, but that sounds pretty sweet too.
*EDIT*
I just found
this link that explains all the ways Chrome can/does communicate with Google, and how to disable them. Lets face it, Big Brother is upon us, and unless you are running through the TOR network 24/7, you are being logged in some way shape or form. At least its a nice company like Google that has my information and not those assholes at Yahoo
