Yes, take it to the dealer and ask that the windows be adjusted. They are made to be adjustable so that they can be tweaked to the top if it ever falls slightly out of alignment. Just like anything the car will settle in after the first 500 miles or so, so a little movement of stuff is to be expected. It should be like a church inside with the top up. Mine is.
The brakes in our '08 and '11 C70s were/are very soft...the XC60 feels like it brakes with more authority. Just have to remember which vehicle I'm in while driving on our 65-70mph 'highways' that have stoplights along the way! There's not a feeling of LACK of braking power, just has to be applied more forcefully in the C70(odd, compared to our XC60 and previous XC70, given the weight of the vehicles). We had warped rotors replaced on our '08 @ ~25K miles and the brakes felt exactly the same with the new rotors...soft but capable when prompted.

I have the same noise, I can tell is window related but not just the window. It goes away when its lowered or when the window is closed and you hit the up button again. What does the dealer want to fix this? Wich I could figure out how to take the door cover off...
