The specs are literally the reason why people would buy this. It's basically the best device we have available that can be used as a base for devices handling secure computation, or software handling secure computation. Think of a FIDO2 key, or a gpg smartcard, all secure and verifiable

Ehhhh... I'd recommend a Teensy instead, or a variety of other microprocessors. At $72, this is awful value. And there seems to be no specifications with regards to power-consumption.

Teensy 4.1 gives you Hardware Floating point, 100 MBit Ethernet, USB, 600MHz, 1024kB of SRAM, 7MB of Flash for like $35 and within ~100mA of current usage at this 600MHz speed, meaning it easily runs off of AA Batteries for over a day with just a bit of idle/sleep cycles.

there are use cases, such as security, where you want as few instructions as possible, so a full ARM processor isn't the best idea. You may want to read the threat model page: https://tillitis.se/products/threat-model/

Wow.

I have no idea what I'd use it for (or even how to use it) but I want one!
