I quickly read the translation, but I'm already quite familiar with these kind of devices so I didn't need the background.

This is a good writeup. I wish there was more writeups like this because invetibaly if it is on youtube, it is sponsored or a paid review.

Even if the device is free remeber youtubers, that's just another way of paying for an ad.

I agree that it's different and that's a good thing. I wanted to like it.

The main issue I have is the pin server. Not the concept of it actually, but the problem of trying to run your own.

My guess is nobody has really tried this. I did. Got the pin server running on my own machine. You had to factory reset the jade (it's been a year, idk) and then you had to add the details of the server, IP, etc...

Problem is, if that changes, you can't unlock the wallet. So the url of the pin server is bound at creation. If you happened to dhcp and we're using IP address on a LAN, oh well.

So these kinda foot guns are not up front and because no one complains about them, I doubt they tried.

The esp32 is also not a chip known for security...

But yes it is designed for a different use case.
