I can't speak for everyone, but I'm sure that a majority of us early adopters bought the watch not because it was just a shiny new gadget, but because it meets our current needs exactly. I was a bit hesitant on buying a first gen device, but I honestly can't think of any issues I have with my Steel Watch. The biggest and only one that comes to mind is that it takes a while to turn on compared to an iPhone or Mac, but then patience is a virtue. Battery life on it has exceeded my expectations and I can usually get more than a day and a half with my Watch with moderate use.
I love the convenience of wearing a watch that motivates me to be more active while also keeping me informed on current events with the NY Times app and giving me relevant notifications as they appear. I hardly ever use my 6 Plus anymore, which is hard to believe considering how three weeks ago I was so attached to it. The 2nd gen will definitely be better, but why endure the wait if the current product does all that you want/need it to.
