This is bunch or crap and incorrect information, and ledger has the worst hardware wallets in the world.
Ledger model S stopped manufacturing, ledger X uses worst batteries ever, they have a bunch of old models that ended up in graveyard, not to mention all the leaks, closed source code, recent disaster with Rec0very crap, etc.
I do not dispute the fact that the Ledger nano S has been discontinued, which is absolutely natural since they are replaced by the nano s plus model, but they still receive firmware updates.
You also write about the low price of the Keystone, but I bought my Keystone Pro for $169 and pretty soon I'll have to throw it in the dustbin. I also want to remind you that they previously released one of the most expensive wallets in the world
Cobo vault worth $479, which someone probably bought and already threw in the trash.
But if you like to throw away wallets a few years after purchase and then buy new ones, then I will not argue with that, that's your right.
