rumor has it that the 17 in mbp will have an 8x dual layer burner.......i could care less about that as i never ever burn dvds anymore. but, the one thing i want is a 160gb HD option, and really really badly......think theyd let this be an option on the 17 and not the 15? or would both get this option? and when do you think they would have a 160gb hd in them?
