I bought the first watch, enjoyed it when no one else had one for a couple years. Then I bought the series 3, then 5, then 7. People reading this probably upgrade phones yearly even though my sister still uses iPhone 6 and it works fine. I always buy first-gen and enjoy the products, I don't care if it's obsolete in 3 years, if it succeeds it will have new and better versions (unlike the trash can Mac Pro I had, it never got a new version). I only buy mid cycle products when I NEED them for work otherwise I buy my personal stuff on release date.Most people hate it because first-gen products tend to be a mess.
Look at first-gen Apple Watch. In less than 3 years it was practically unusable. The Series 3 held up way longer.
Same with iPad. 2nd gen iPad lasted much longer.
