I too visited an Apple Store (SF Bay Area) yesterday and tested products. The iPhone 17 Pro Max in particular, A-B testing against my 16 Pro Max. My observations:
• Five hours after opening the store still had a short line to enter the busy store. Most folks looking at iPhones. I was the only person trying to do any kind of image capture comparisons among scores of people. Probably a good thing, because it seemed that the constant 5-hours test usage of the iPhones on their MagSafe mounts may have been causing some camera performance anomalies due to heat. Hard to tell though.
iPhone 17 Pro Max
• The new tele lens is a huge improvement.
I am a photographer, and the new telephoto competence makes the 17 Pro a must have for me. Those here that whine about the definition of "8x tele" simply do not get it. These 3-lens iPhone camera systems are different from the one-lens ILC the whiners are trying to compare to. What matters is real-world capture performance, and yes the 12 MP Apple chooses for its marketing metrics is totally reasonable.
[P.S. shoot RAW captures and keep the iPhone camera still.]
• The lack of a gray or equal iPhone Pro color choice absolutely sucks. Apple deserves to lose sales because of it. If the tele lens improvement was not so important to me I would stay with the 16 PM. I verified my reluctant preorder choice of 17 PM silver as the least offensive color choice to me, but I strongly dislike the bright white ceramic back. I would much prefer a light gray ceramic back that did not visually "pop" like the white does.
Maybe next year Apple can bring back the far more elegant titanium alloy frames combined with some muted ceramic fronts/backs. I doubt it though, because they are probably saving a lot of money using the cheap-looking aluminum alloys.
• The aluminum alloy frames present as much cheaper and inelegant. A clear aesthetic/cosmetic downgrade from the titanium alloy 16 Pros. Probably a durability downgrade too, but we can not make that determination based on a day or on a week of clickbait internet nonsense. It will take real-world months.
AirPods Pro 3
• My need regarding AirPods Pro revolved around the fit. The AirPods Pro 2 constantly fell out of my ears. Maybe the new foam works as advertised by Apple, because the new AirPods Pro 3 design did fit my ears much better in walk-around testing. Enough so that I bought a pair.
• Testing the various tricks of the new AirPods Pro 3 in the noisy Apple Store suggests that they work and sound good as expected. ;~) I could not A-B compare against the AirPods Pro 2 however, because I only have one AirPods Pro 2 (the dog chewed up the other one after I fell asleep and it fell out of my ear).
• The case for the new AirPods Pro 3 seems quite large. Hopefully that means even better battery performance.
