Well. I've got Vista coming down at the moment. About 7GB worth as I want the 64 bit version for my Ferrari and the 32 bit versions for my other machines.
The Office Beta uses some download client.
Be warned- it gives dodgy error messages.
'The email address is invalid'
actually means
'There is so much trafic hitting the server that I can't log you in... but I'm going to give you a dumb error like cannot find user account just so you have to go through the pain of going back to the sign up website... which is also getting hammered....'
