The rumors of the AW2 rekindled my interest, but I'm having a hard time deciding which size to buy. I tried both on in a shop (http://imgur.com/gallery/hbyUB) and I have to say that both looked smaller IRL than on photos. Nevertheless I'm not fully convinced that 42 is the way to go. Based on the photos, which one would you say looks better? Unfortunately, both devices had empty batteries, so I couldn't judge how much more crammed interface elements and text are on the 38mm. Has anyone here compared them in depth concerning differences in usability?
