I don't buy it.
Most of these laptops will be used by Joe Blogs (not a typo) sitting on his couch watching American Idol, or sitting at his desk... Where his Mac used to live. Like it or not, Apple is bringing a preponderance of fashion firepower to bear and their laptops are simply must-have gadgets among the proles, not unlike the Razr phone of the past (except a hell of a lot more expensive). Everyone who can't afford an Apple laptop (whether monetarily or productivity-wise) "needs" to buy something close - so that'll be another laptop, then, because it's roughly the same shape.
Everyone wants to be seen as mobile, even though they're really not. Those of us who ARE truly mobile have had laptops for a decade and generally hate the damned things but accept them as a fact of our lives. Everyone else just wants to be able to surf porn on the toilet and watch Youtube videos during TV commercials - they don't need TRUE mobility because they have a computer at home, and a computer in the office. They spend the majority of their lives either at home, or in the office, or commuting between the two, and occasionally engaging in recreational activities that you have no business bringing a laptop to.
People who swear they're part of the "mobile workforce" because they own a laptop make me laugh. They'd inevitably get even less done if I gave them a plane ticket and hotel reservation in Las Vegas and told them to take their laptop.
