why would they care what you use the internet for?
Google collects anonymous usage data. Really not harmful imo. If you have the sync thing turned on, it'll store your bookmarks and browsing history (I think this one is off by default) but it's not going to be directly accessed unless there's a court order. So basically, if you're researching how to build a bomb, don't use chrome. Otherwise, it doesn't really matter.
I like having all my bookmarks, history and other things synced so that when I go to use other computers I don't have to try and remember my password. Well I should not be using chrome then

Yeah, it's a pretty nice feature. Being able to sync with android is probably the best part.
