I know that some people (especially those who know more about tech) found that the switch campaign and ipod ads were a bit lame... But I think that they did Mac the world of good. They weren't aimed at existing users, they were aimed at people who were sick of Windoze - and they got the message across hard and fast. Good ads - not whizz-bang - but in terms of recall and effectiveness, I bet they were more effective than 90% of other computer ads...
On the new ones - there's nothing new here at all - it's more 70's than anything else. Come on, guys, that's like patenting something as generic as an...er...apple...for a trademark. I'll shut up now.
