I totally agree on the mail app - the phone issues I got used to pretty quickly - I’m assuming these will be fixed with rolling updates. When I bought my Surface Book, I went through about 6 months of occasional frustration, but now it’s 99% awesomeness. Product cycles and pulled-forward introductory dates seem to slice off about 20% of proper development on OS related goods these days. I bet Samsung is kicking themselves right about now for ignoring that EE who said, “boss, we need more time to solve this overheating issue.”
