I'm not technical about bitcoin, but consider myself tech savvy. My take is: in any setting you ALWAYS should have backups, so, I'm not seeing HWW as the security panacea because even if it's virtually impossible to exfiltrate data from the devices, your seed/words/etc should also be in a different medium, which is not likely to be more secure. You know, the whole setup security is as secure as the weakest link and that... That being said, I do think they're amazing devices and the use cases I see are a. convenient secure signing (though on-chain txs will likely become less frequent); b. secure seed generation, with considerations. My take is that a 1 key (12 words) + passphrase, backed up in different locations with redundancy is as secure as you probably need without risking losing funds due to overengineering the crap out of your wallets. I dunno, just random thougts, I hear opinions
