SIZE: I have small wrists and was certain Id like the 38mm but it just felt too small. The Apple Watch (non sport) felt too heavy. The 42mm Apple watch Sport was perfect. I prefer the lighter weight. I ordered a 42 and 38 so I think I'll keep the 42 and cancel the 38. I share the sentiments of others who think the 38mm will be too small for most men. WATCH: it took me a few mins to figure out how to navigate it but once I got the hang it wasn't bad. Glances is going to be the best feature. I honestly don't need this watch and can't think of many things it will do to improve my life but it felt and looks nice. I think the App Store is what will really make it awesome but will take a while for apps to show up and take advantage obviously.
