Sounds like a way of making more money to me. I can imagine a lot people will buy one of the basic editions then find they need one or more of the items only to be found on the other editions and then have to buy another copy. It seems to me to be totally over the top. Why not just create 2 editions like we have with XP Home and Pro or 3 if you count the Media Edition and give people the option to install say a basic or advanced setup. Surely that would be better for the user, though perhaps not for Microsoft.
