As the title says I am trying to decide on keeping 38mm or returning and ordering 42mm. I've tried on the 42mm at the store and it seems a bit large but having more screen real estate would be nice. The 38mm is a tad bit too small but seems a bit more proportional on my wrist as I apparently don't have as manly wrists as I thought LOL. I really need a 40mm LOL. Is anyone else stuck on whether to swap out for the alternate size? I have until Friday to return this one. The sad fact would be going without an Apple watch until possibly June if I did return the 38mm. I know it's a first world problem but who better to ask than my fellow iMore forum family?
