I was debating this very question with a few friends this weekend.
I have 12 bands that I have bought all from getting the AW3 this year. This is my first Apple Watch and I love it as is. I would love to be able to continue to wear a good portion of them as I like their style and I wouldn’t want to have to try to replace them in the future. Yes, I would be a little upset that my bands no longer work with the AW4. I have some favorites!
That said, I’m of the mind that Apple isn’t worried whether or not new bands would have to be purchased for a new Watch release. Look at their other products, like the iPhone when the 3.5 jack was removed or with the change in slimness in different generations of the iPad making it so an old case wouldn’t work with a new case. Apple moves design forward and new accessories get released to match the new design. I’m surprised that anyone would be so upset if Apple’s design and technology philosophy extended to the Watch. I’m expecting it to happen at some point, whether it will be this year or the next. That’s just Apple.
I admit a part of me didn’t really think about it at first. I was excited to have my first Watch, so I was getting whatever I liked (fortunately, quality, low-cost, third-party bands). Then I thought about cases I would buy for my iPhone that I have tossed over time and stopped to think. If Apple does make changes, I’ll have a drawer full of bands that will work with this Series 3 only. Maybe I’m going to slow down here and see what comes up in September. This was before I saw any rumors of size changes.
I won’t get mad at Apple if they do end up making changes. It will be my lesson learned to not get carried away with bands in the future.
