Nano S is better for me by security reasons, as I don`t like the wireless feature: it`s too vulnerable point of the X version and will ever be.
Nano X is just more comfortable with the better screen, lights and screen dimentions. However I don`t think they worth the security risk.
to be fair, you can simply disable bluetooth on the nano X and use the USB-C cable instead. you can use it just like a nano S except with the better screen, backlight, IOS device support, etc.
the bluetooth functionality can't compromise private keys, which are still held within the secure element. even if your bluetooth connection were hacked, your consent is still required to sign a malicious transaction.
Did they make any significant changes in the secure element and the storage of private keys? Can the new device be considered safer in any way compared to the S model? Does anyone have some more info on that?
still can't find much info about this,
but according to this techcrunch article:Ledger now uses an ST33 secure element, which is slightly more secure than the previous version ST31. Now, theres only a single chip, connected directly to the screen and buttons, which reduces the risk of having someone compromise the information on your screen.
