As someone who is a day 1 adopter, let me give you my insights as to what I think:
- The watch is DEFINITELY bigger and thicker than the Series 8 and noticeably heavier, despite the lighter than stainless steel titanium.
- The screen brightness is noticeable in direct sunlight, but not mind-blowingly different (but still definitely noticeable).
- The bigger crown is grippier and is not as smooth as the Series 7 from where I came from.
- The biggest aspect that has me debating on whether to keep it or not is the look. At first, I didn't think too highly of it, finding it kind of weird, but then the look grew on me. Still, I have my gold stainless steel Series 7 that I compare it to and I definitely find the gold more attractive (I know, I know: it's supposed to be rugged, but rugged watches can still look good: just look at dive watches!).
- Although no damage on mine, this titanium finish is probably not as durable as you may be led to believe: my gold Series 7's PVD coating has kept it looking almost completely new since I got it as a gift for Christmas last year (a slight hairline scratch that may have very well been from the factory that I missed until MUCH later on is the only exception). The screen, however, has a noticeably thicker, less smooth feel which is probably because Apple made that more durable.
- Speaking of the screen, it's not really any bigger than the Series 7/8: it's basically the same size because of a thicker bezel that's also slightly more rounded, making the Series 7/8 look more square, interestingly enough!
- The exclusive Wayfinder watch face is pretty cool, fitting up to 8 complications on one face (not unlike certain other faces, like Modular). Also, it's cool to be able to make everything turn red for nighttime viewing, which I've already done a few times now. My only complaint about it is that, to make everything fit on it, including the cellular that automatically appears in the inner-upper section, the text and complications are smaller and, since the screen practically isn't bigger than the Series 7/8, it's not an optical illusion: it really is smaller, albeit not too much!
With all of the above mentioned, I'm still debating if it's worth the almost $1,000 with AppleCare and tax to hang onto; my gut says "no", but I'll miss the features that it has, including the doubled battery life. Then again, with waiting until next year, I would be
shocked if Apple didn't implement at least the better battery life and brighter screen in next year's Series 9 (just like how the pro model iPhone features drip down to the regular models the following year, like Dynamic Island). Also, don't forget that we're overdue to have a new processor, the S9, that's an ACTUAL upgrade from the Series 6's S6 circa 2020, which has been rebranded and repackaged in the last 2 watches that succeeded it! At any rate, you have at least 14 days to decide if you bought it in-store; 28 days if you bought it online and set up a return by the 14th day, which should give PLENTY of time to make an informed decision, which I know I'm in the process of making, myself...
