Stop calling them hardware wallets and start calling them signing devices.

"Signing device it is, then. Don't want to confuse my followers with old-school terms Can't have people thinking I'm still using Bitcoin 2.0 #SigningDeviceSquad #CryptoClarity"
It's all marketing. Like blockstream calling Liquid a layer 2 instead of a side chain.
my hardware wallet is my savings account.
There are distinct differences between the two terms.
Most people mean the same thing when they use them.
What is the different?
At least for me, the difference is a hardware wallet stores your keys on the device. That would be something like a jade or a passport.
A signing device is just that, a signing device. It doesn't store your keys long term. You have to load your keys on it to be able to use it to sign your transactions. Like a seed signer.
A hardware wallet can sign your transactions for you because it stores your keys on the device, but a signing device is only used to sign transactions.
I guess to put it even more simply, at least for me it comes down to where the key is stored. On device or off device. On device, it's a hardware wallet. Off device, it's just a signing device.
