I still don't understand who should buy this.
If you have an older iPhone, there's little here to entice you to upgrade, unless you have an SE or an iPhone XR or older.
If you are an Android user, there's little here to tempt you to switch platforms,. This is especially true if you are outside the US; the Samsung Galaxy S24 is 100 Euro cheaper than this in Europe, for instance (not the FE, the regular S24, officially on Samsung's website), while the Pixel 8 (not 8a) is the same price. If you are in the US, you're probably already an iOS user or not in the market for a phone this expensive.
Even if you did decide to buy a new-to-you iPhone (maybe you do have a very old iPhone, or your phone just broke, or you did decide to switch to iOS just now), the older iPhones are fierce competition. For instance, the 13 Pro can be had, brand new, for less than this, and is a better phone (ultra-wide and pro cameras, MagSafe, 120 Hz display) unless you strongly care about having the latest chipset or USB-C. Even though Apple isn't reconverting them into SE models, they're still attractive. And there's a whole used/refurbished market too, of course, if you don't care about the latest, greatest and shiniest.
So, this is for... the Goldilocks buyer who absolutely wants a new iPhone now and absolutely won't settle for an older chip and Lightning but absolutely won't spend more for the regular 16?
I'm sure Apple has done its homework, but it's hard not to see this as either a decoy model to make the 16 more attractive and/or as a way to screw over those that don't know better (perhaps walking into a carrier store and just getting the cheapest iPhone they offer with no further consideration, as the review suggests).
