My personal needs are probably much fewer than those of others. From the top of my hat:
- listen to podcasts
- control spotify
- control oura
- phone calls, sms and signal
- mfa provider
Everything else (including cameras) can be stripped away for my dream phone if it gives me a smaller device. I have never designed phones unfortunately, so I’m not aware which components take significant space. The camera I suppose, fm radio, ir and microsdxc? Perhaps the removable back cover?
That said, my maximum viable product as I said is the iphone 13 mini, which is not 5”, but actually 5.4”. What the mini got absolutely right is that they didn’t compromise on the build quality. The mini is exactly as premium as the regular iphone 13, just smaller.
