I'm excited about the iPhone Duo. Considering replacing either my iPhone 17 Pro Max or the iPad Pro M4 & Apple Pencil Pro for the Duo.
Maybe the latter, even though I have to compromise some features, i.e., downgrading from Apple Pencil Pro to the USB-C Apple Pencil. Duo supporting Apple Pencil is one feature that sold me. I found that I use the iPad way less than I used to. Still heavily relying on my Mac and iPhone. No pressure sensitivity is a bummer, tho, as I've been using Apple Pencil 1 since 2016, which has this feature.
I also take and edit a lot of videos, and I absolutely love my 17 Pro Max's camera system, which is better than the Duo that lacks the telephoto lens (which means no 4x and 8x optical zoom). I could keep both the iPhone 17 Pro Max and the Duo, but I have to hope that AT&T will offer the iPhone Handoff feature. At least the 17 Pro Max can still be a great camera.
Can't sell/trade in both because that would be compromising too much - pencil, camera, LiDAR sensor, etc. At least in 2026. But in the foreseeable future, I see that I can have an iPhone Duo that can function as a Pro iPhone and Pro iPad combined. Imagine I can just have one pocket device to handle many tasks on the go.
