Thanks for that. Makes sense, I guess.

I thought at first that the discs I would get when I bought the crossgrade would be update discs only, but looking at them again and after what you've said it looks as if they're actually full install discs. There's certainly no mention of "crossgrade" printed on the discs: that's only on a cardboard sleeve round the outside of the box.

I'm still gonna download the installer from the site just in case though!
