Negative. Vista Upgrade Anytime was offered as a download. I would not recommend it, or any other substantial download without the guarantee of a repeat download if the first one craps out. This happened to a PC Mag journalist in the UK who tried VUA download. His conclusion - always, always go for a hard copy.
I thought that Vista anytime upgrade just contacted a web server to charge your card and unlocked files that were on the DVD that you already had - it never downloaded anything other than a new license file.
Anyway, I was referring to offering ISO's of it's products - it's only really offered to businesses under volume license agreements.
Anyay, the point is moot - large downloads like that are not viable for customers unless QOS can be guaranteed. It gets harder to do that the longer the download is.
