I'm passing.
I was really tempted by the ProRes recording, but I don't think that's at all practical considering how big those files are. The cloud isn't an option, so the first thing I looked for was to see if they switched to USB-C... Nope, still Lightning. Hard pass.
I'll probably keep the 11 Pro for another year and then upgrade to something else. It depends on what Apple does in the next iPhone/iOS 16.
Also, the iOS 15 update is quite thin this year, which typically means the better features next year will be exclusive so the new iPhone models ;-)
I can't use an iMac or MacBook due to Apple using PWM to manage display brightness. This gives me some serious tension headaches and migraines. Suffered for years before I realized my iMac was causing them, and had to get rid of it. The iPhone is too inconvenient to use with a PC, and while this is generally avoidable the use of ProRes for video acquisition will basically turn the phone back into another dongle... which requires a proprietary USB Cable, etc.
Just not an inconvenience I want to deal with.
I've probably used my 11 Pro a cumulative 20 hours or less since release, because I'm really over the inconvenience. I still use my Note 9 for 90% of things. I use my iPhone only for banking apps.
All this has taught me a valuable less regarding "how good are these upgrades, really?"
