Back when vista came out you wouldn't have had 7 to compare against, in contrast vista was superior.. the point is both 7 and vista have had a snowball effect in media.. only they went down different sides of the mountain.. specifically why they went down different sides is bizzare..
I can only put it down which side you start on being completely open to whoever 'fires first'.. in vistas case, microsoft were so quit about it the only news people had was of its complete disasterous restart.. with no counter positive its negative spin got to big to stop.. with 7 it was clear they identified this problem, and kept everything about 7 quiet until they started blogging and generally talking 7 up.. in this case microsoft 'fired first' and managed to set 7 off with a positive spin.. the media being useless wankers that they are justified their stupidity and ran with it..
Not to say 7 doesn't deserve this credit.. it does, but so did vista.
