Last week Sony announced its contender, the Vaio X, which is uber thin at 55mm and almost HALF the Air's weight - see here Macrumors Vaio X thread, the specs of which have not been finalised (but people predicting an Atom processor given its thinness and enclosed in carbon fiber. Specs though have not been finalised for this yet, the display models so far are not final spec. Well Dell today announced a "9.99mm" thin laptop: http://www.engadget.com/2009/09/09/dell-teases-new-ultrathin-adamo-xps/ http://www.adamobydell.com/xps/choose-language.html Again, no specs at all at this stage, beyond the thinness. 9.99mm is truly incredible! As Engadget mention, that's thinner than the iPhone! I just seriously hope it's not an Atom processor, otherwise my interest in it would almost instantaneously evaporate. Sony and Dell's cards have been (partially) dealt. They both appear impressive at this stage so far. Enter Apple. I can't wait to see what Professor Jobs has under his sleeve... exciting times for premium ultraportables!
