The ones who still own their data? If data is money, they can also afford to buy new phones. iXpand USB-Lightning drives are supported by some iOS apps which process large files, e.g. media playback and editing.

There's no need for everything to be lowest-common-denominator. Product management is not statistics, it is aspirational leadership for upward mobility in human values, including but not limited to function, form, and creative power. e.g. a tiny minority of humans create art for millions, yet both can use the same device + accessories, if devices are not neutered.

iPhone can backup to a PC or NAS wirelessly, no reason for a cable other than charging.

WiFi is vulnerable to many, many, many, many attacks.

How do you backup iPhone to NAS? Do you mean mounting a NAS drive on a PC/Mac and then using WiFi for iTunes backup?

I'm curious what your threat model is. State actors? Hanging out at DEFCON?

Corporate IP protection, which these days includes state threats.

A recent WiFi vulnerablity, https://www.fragattacks.com/

> The discovered vulnerabilities affect all modern security protocols of Wi-Fi, including the latest WPA3 specification. Even the original security protocol of Wi-Fi, called WEP, is affected. This means that several of the newly discovered design flaws have been part of Wi-Fi since its release in 1997! Fortunately, the design flaws are hard to abuse because doing so requires user interaction or is only possible when using uncommon network settings. As a result, in practice the biggest concern are the programming mistakes in Wi-Fi products since several of them are trivial to exploit.

I do on a daily basis, but I'm a bit of an oddity in that I've strenuously avoided the shift to streaming music. I don't want all the music. To me that's the same as having none of the music. Heck, I don't even want all of my music. I have a set of smart playlists that keep my phone loaded with a mix of less played and less-recently played songs that give me a set of music that changes every day (although it would take me a few weeks of continuous listening to listen to everything on my phone as it is). I've found wifi sync to be flakey enough that I do my daily sync with a cable.
