hi to all, i have seen now both the 38 and 42 MM sports apple watch in a store. which do people find the easiest to use? i am totally blind so would be solely reliant on voiceover. can the small screen on a 38 MM make it difficult to use the watch just using gestures to find complications, do swipes etc? i liked the 42 but finds it "sticks" out if that makes sense, on my wrist. whereas in contrast the 38 mm seems very unobtrusive. how is battery life on a 38 MM watch?
