So, what this is saying is that it's gone over remarkably well, but a couple people had trouble.
A couple people are bound to have trouble even understanding how to reply to this post. Sounds to me like it's gone pretty dang smoothly, considering the huge scale of the release.
Then again - I have heard from a fellow I know at CompUSA that the sales of Vista have gone FAR slower than they anticipated - with lots of copies not even unboxed from the cartons...
He also said that they have about a week's worth of backlog in the tech/repair dept. at their store. He said that people are trying to install Vista on machines that they really shouldn't - between hardware incompatibility, to already bunged up XP installs (and one poor woman that actually tried to install Vista on an old 98SE machine...ugh), to machines that just need to have the drive formatted because they are so badly infected.
And that people don't need to buy the full version!
