This, same thing with Trezor hardware wallets. I just usually default to the Ledger Nano X recommendation because most of the people I know use iPhones. 
Similar adapters most probably exist for each modern modern phone, at a couple of bucks (I've bought MicroUSB and USBC ones at under 1$ back then, but for iPhone they seem to start at 2-3$).
So still no Nano X on my list
As for the Nano X being overpriced, I don't blame you if you think it is. Outside of Bluetooth, it has a significantly better build quality heavier and better buttons and all that.
Don't forget the bigger memory, i.e. space for more shitcoins' apps. Convenience is never cheap and I do understand the iPhone people prefer convenience, even if it's more costly
