The "twice as fast" and "half the price" ads were rather disingenuous. The "most advanced operating system" -- what? that's true only if you consider how great it looks. Otherwise, we can easily rattle off many Unix variants which kick OS X's ass when it comes to performance. Xcode: "the best IDE ever". MobileMe: "you can't believe this is a web-app, unheard-of usability in a web-app!" It just doesn't stop. They go overboard.

As for the "I'm a Mac" ads, they are not that bad at all.

Disclosure: I own an iPhone and am madly in love with it. I also own a new iMac, and love its looks and would like to make OS X work for me, but have not been very successful at that. Perhaps because I am just used to Linux.
