It is a completely different device.

Flipper Zero is for the physical layer: radio, RFID, IR, etc... It is based on a small microcontroller and is mostly "bare metal", think Arduino, ESP32,...

Flipper One is for the network layer: Ethernet, Wi-Fi, 5G, etc... It is a "real computer" running Linux, like a Raspberry Pi.

Interesting. So the model number corresponds to the OSI network layer?

No. There was never an OSI "layer zero", and it's unclear how the OSI model would apply at all to functionality like RFID card reading.

I'm hoping for Flipper 8 and Flipper 9 now.

Jokingly I've always said layer 8 was people, 9 was management, and 10 was budget.

The two that I've heard are money and politics.

RFC 2321 suggests that they are "political and religious" layers. https://www.rfc-editor.org/info/rfc2321/

   In this document we introduce a new hardware-based tool for diagnosis
   and repair of network related hardware and software problems. This
   tool is best suited to addressing nondeterministic problems such as
   those described above. This tool has broad areas of application at
   all levels of the OSI model; in addition to uses in the physical,
   network, transport and application layers, it has been used to
   successfully address problems at the political and religious layers
   as well.
