Just bought one of these

>the difference, obviously, is that at the end of either process you are going to HAVE to plug into a computer connected to the internet
no that's not true.
An offline computer generating a transaction is basically no different from a ledger (an offline usb-sized single-board computer that creates a transaction). You can broadcast the transaction from anywhere you like without the need for a private key after it's been signed offline.

it's about trezor, not ledger.
Ledger wallets are actually secure.

I think they still would need to physically hack it. It's equivalent to connecting over USB. The device has only a limited set of instructions, such as sign a message or transaction. Once those instructions are sent to the device, it acts as a black box and only sends back the result.

by the magic of fairy dust I assume. Nah dude they're basically the same and claiming anything related to computers is secure is just delusion

and when you plug that USB into a computer that contains malware, and the USB then gets infected with malware that logs all events and waits until an active internet connection to send this info back to the guy who made the malware?
you can say its extremely unlikely all you want, but the fact remains that this is a tangible risk using a non hardware level secured USB device

>when you plug that USB into a computer that contains malware
what part of "boot a secure OS from USB" did you not understand?

what part of connecting to the internet gives you the chance of being infected by malware do you not understand?
tell me right now that there is a single OS that has 0 vulnerabilities and i will personally piss my pants laughing at how retarded you are

they have a secure element, a chip specifically designed to thwart physical attacks.
Yes, it can still be broken if you have the right tools, but it's orders of magnitude more expensive than breaking a trezor, which uses a normal arm mcu. In particular, secure element is designed to be completely immune to sidechain attacks (undervoltage, temperature differences, etc).

>sidechain
sidechannel*, lol.

listen man hardware wallets are secure. And they are convenient. I'm not dissing offline software wallets. They are also very secure if done properly. The problem is, you sound like a neckbeard Jow Forumstard who thinks everyone has the time and knowledge to set up a complicated system for securing their money. Newsflash, they don't. Hardware wallets are great for mass adoption because they give you near the same security (if not more) of an offline software wallet, while being smaller and easy for normies.
