> First one is simple and focused
First time I've heard anyone call the Flipper Zero "simple" and "focused", most people seemed to have considered it a "swiss-knife" meant to just house a bunch of features and radios, meanwhile the One has less features but more connectivity and I/O.
But apparently you're not alone in feeling this, but I don't understand what from the submission makes you and others believe so, what exactly gave you this impression?
Well the first one was a microcontroller.
And this one is an 8-core Arm computer and the project has ambitions of some notoriously difficult things: no binary blobs, full mainline support (including a NPU), reinventing small-screen UI for more serious handheld computing, and supporting a ton of high-bandwidth interfaces.
This is not a simple step up in difficulty.
