Well, this has not anything to do with your questions, but.. since you are waiting for the Powerpack to arrive, just a quick tip about a strange hitch that occured during install :
At a certain point (with the International version, that is), the install may freeze. Can't tell you exactly when but..
Anyway if ever this should happen to you, just hit the F12 key and that will start again and finish without any further
interruption.
Also, try to configure your internet connection at the end of install, it is in my experience, MUCH easier.
Cheers
