... I would certainly not purchase one without a certificate from Apple (the way other PC manufacturers are doing) to say that it is "Vista approved" if I actually intended to run Vista on it.
I can totally understand that. But I wouldn't bet Apple will do it. True, they want new comers to feel safe by knowing their newly acquired Mac will also run Windows. But ultimately, they want these people to use Mac OS X. They want everybody to see Windows as a back-up. Not as your main system.
I'm not saying it will not happen - but if it doesn't while everybody tells you Vista works fine on an Intel Mac, will you still refuse to buy a Mac?
