Hello, I am thinking about buying the watch series 2, however I am still unsure about the watch dependency on the iPhone. From what I read, the watch OS 2 is able to connect to Wifi without iPhone and also has support for native apps. So let's say that I forget my iPhone at home but at work (or any other place) the watch will be connected to Wifi. Will the Watch be able to receive notification for email apps, messaging apps (such as Facebook messenger) and will I be able to act on those notifications (reply)? And one more question, this one is regarding the aesthetics I am undecided whether to go for aluminum or stainless steel. To be honest, I am leaning towards aluminum first because I am not sure if the watch will fit my workflow. So in terms of aesthetics and style (the watch will be paired mostly with leather strap and worn with shirt and jeans), do you prefer the silver one or space grey? Thanks!
