Highly highly recommend going air gapped w/ SD Card. No need to introduce any additional attack vector whenever you can avoid it.

This is why blatantly recommending cuckcard to everyone without assessing personal needs is dumb.
Even more dumb because it's not Free & open source.
What happened? Is coldcard bad now?
I am just a poor ledger refuge waiting for cold card in the mail
No, it's not bad. With #Bitcoin you've gotta understand that nobody ever agrees with everything.
The MK4 w/ SD airgap is a clear upgrade to your Ledger.
More importantly, what wallet software are you going to use with the cuckcard?
Not open source :(
