Carbo... not really. The 10MB express is the minimal, then it goes online to download the rest that is needed. With the full 106MB file, it still loads only what is needed.
BTW: Looks like there were some people that were wrong when they said "it was not the final version." That "leaked" version was identical!
I will say this, the servers that Microsoft use are really fast. Even with everyone downloading (as of 5:30pm) today, I was still able to download that 106MB file in 4 minutes (cable). You know they got a fat pipe 😀
