apple always do things their way, it's whats makes these board interesting trying to predict them.
If you want to see a waste check out apples uk Adverts, they are a waste of money they only preach to style and people who already know and own a mac.
The flip side of this is o2 who's iPhone adverts actually shows you what you can do with the phone, if apple made the same advert it would simply be a video of the iPhone rotating with some tune playing
You sound like your new to all this, Im far from a mac veteren, I left XP in my rear view mirror about 4 years ago after I came into ownership of 2 ibooks (g3 &g4) that had been thrown out after a school fire.
My first show was a september ipod show the Mac Mini got bumped and I bought One, the following April I bought a Blackbook.
I Will tell you one thing about apple product releases and other guys will confirm this, dont put your expectations too high, apple always give us something but they never give us everything, because what you want isnt what apple think you want
