Pretty much. If I have the exact same vista that everyone else runs, the problems are either there or non existent. There can't be a bug on one copy and no bug on another copy of the exact same OS.

I haven't seen any problems, but if you say you've seen, them, I'll take your word for it.
Quote: "But nothing Apple has done is illegal. They're allowed to advertise like that. It doesn't even have to be true!"
Yes, it DOES have to be true. Otherwise, its called, "false advertising" and THAT is illegal. If I put out a commercial saying that you were a transvestite, and that you ate puppies, you could sue me for false advertising and defamation of character.
Quote: "And what would Microsoft gain from filing a lawsuit against Apple"
They COULD gain control of Apple and eliminate some competition. Not saying that would be likely, but its possible.
