The Nano X has a slightly better screen
That may well be true, but the screen isn't used for all that much on the Nano S as far as I can tell, at least for basic sending and receiving of coins. It functions and looks just fine IMO, and I'm not sure I'd care all that much if the Nano X had a better display.
Unless you desperately need Bluetooth functionality (and the Ledger Nano S is still compatible with non-Apple phones via a cable), then I don't think it's worth paying double the price for the Nano X unfortunately.
Yeah, that's the main reason why I haven't bought an X, because I don't need the additional functionality it offers and I'm not willing to pay the extra money for something that isn't necessary. I really like the "Over the Moon" model, though and I was considering getting one if it ever went on sale, but it never did. Oh well, not a big deal. Ultimately if I were someone who was going to buy a Ledger for the first time and for whom cost was a factor, I'd definitely go with the Nano S.
