I read the page but not being an expert on Flipper I am not confident I can tell the difference from the Flipper Zero.
flipper zero is just a small device with an SMT32 MCU, flipper one is a whole bloody linux computer, with an rp2350
I suppose the idea is it combines workflows you'd use a flipper zero + pc for into one device. Neat in idea, im not certain who it's truly for in practice. A flipper zero 2 with wifi built in and some minor improvements would have been much more welcome in my eyes.
Yeah, they should have included a comparison on the Kickstart page. If you check out the "we need your help" page, that has a chart with "Zero vs One":

The two devices are complementary.
Zero does mostly "radio" stuff (RFID, subghz, etc). One does mostly "network" stuff (wifi, 5g, etc).
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.
