Maybe it's a silly question, but how can the new OS launch apps 7 times faster than the OS of one year ago? These kinds of improvements usually occur with a new hardware, but 7 times faster only with software is... just wow. Ok, maybe they keep your favorite apps in the background so they're always available immediately, but how can't this drain the battery? It's pretty clear that Apple practically said that they did wrong things in watchOS 1 and 2, so do you think that's about it? Bad software?
