While I sympathize with having eSim issues in general, this doesn't seem like the video to complain about it since as others mentioned it has more to do with the carrier than the phone itself. A friend of mine was complaining that no SIM card might be a problem when traveling but someone else addressed that earlier as well. As for me, it was 100% seamless but I was going from eSim to eSim. Last year I had problems with the transition, but that was completely because of Best Buy's ineptitude. But similarly it makes no sense for me to spend a bunch of time complaining about that here.

I never viewed dynamic island or always on as features that would make me want to upgrade, but more as "nice to haves." And I would say so far they have both exceeded my expectations so I'm happy with the updates. I like being able to just glance over at my phone at any time (whether I had turned it on or off) and see the time, as well as the widgets like number of steps that I added. The island is kind of fun to see what will happen with it, but doesn't really change my day to day usage (aside from the pong game which is a pretty fun diversion).
I haven't had a chance to test the camera yet, but I assume it's going to be a win. Battery life definitely seems better; I saw a review from Tom's Guide saying something like 2 hours better in testing but I haven't experienced anything like that. But even with Always On, I seem to be getting slightly better life so far. Oh - 5G - I read about the chip improvement the other day and didn't think much of it, until I was in the bathroom at work yesterday and got a remarkable 1492 Mbps on Speedtest. I was really surprised; that's the fastest download speed I've seen on my phone ever, including WiFi. I did another test in a conference room and got 947 so I don't think this was a fluke. If this holds up in other locations, that would have been worth the upgrade for me personally.
Oh and about the color. I guess since I'm always using a case (even clear ones), it doesn't matter much to me any more which one I get, but I went with the Space Black, and I do really like it. The purple looked nice to me as well but I'm glad I went with black.
