I think they will continue to have them, when else is apple going to get the huge publicity? Just the auro that macworld gives off makes you want to be there. Seeing and using the new products first. I hope to go sometime.
I like the 17" laptop. Who wouldn't want to watch a movie on the road on a 17" screen rather than a 12 or 15? As far as the price... not too bad considering just a 10" portable dvd player is around $1000! Considering how much more functionable a laptop is too.
