I also disagree.

How a laptop can be more usable, secure, cheap, maintainable, tough, portable, conceable than an hardware wallet?

Talking about the laptop complexity you perhaps forgot all the OS stack, it is huge. The supply chain attack for the HW? Did you hear about the libraries supply chain attacks that are popping everywhere?

I used Tails with a volatile boot to sign offline transaction and so on, too; but an HW is a relief in semplicity and user experience.
