I wear a Pebble, which is 51mm tall (case size), fits great, and I know I will want the watch with the larger screen.
i see, good point, i think it would be difficult to enjoy and do much stuff on the smaller screen so im thinking if im spending 350 now might as well add another 50 bucks and get the larger screen,
i just read on another thread that the 42mm model has a slightly better battery life too which i think is a great plus worth noting..
