Until they change the EULA, you're giving Google the right to use anything you do via Chrome...

As for actually using Chrome, I'd hold off until they release the first update at least. They're using an old version of WebKit and its vulnerable to that file download trick. Even if it didn't have that I'd wait to see if there were any other issues or bugs. Let the rest of the world be the guinea pigs on this one...
