$59 for the Nano S sounds more reasonable given the lack of new functionality on the Nano X. Are there any other considerations to make?
The Nano X has a slightly better screen - its backlight is better and it's bigger so you can slowly read anything displayed on the screen (addresses do not fit on the Nano S; the text constantly moves). Also, it has a USB-C port - a small thing which might be important for some people. I don't like having a lot of different cables.
