While I do applaud the idea of "re-thinking the computer for deverlopers", this looks little more than "thinking", to me.
A back of a beermat business idea, pulled through an expensive marketing machine.
My rule of thumb: if something has a concrete price, but the something itself isn't made yet, it's either way too expensive or a ploy or both.
Maybe its a "find if there's need for it" phase. But if you cannot make that "it" concrete, I -and I suspect many more of the target audience- cannot answer this question.
So yes: kudos for bringing up the "developers need other hard and software than general audience" idea. But I would strongly advice to first make it concrete and deliver pieces and parts. Release the DE and OS so we can experience if this solves "problems" that devs have. Finetune that. Again. And again. Then pair it with hardware. Personally, I'd go for hardware thats already popular with devs.
For me, thatd be: Ship me a high end Lenovo, with Ubuntu¹ pre-installed and loaded with software like neovim, zsh, git, ripgrep, chrome, firefox, zed, slack (we all require it, don't we?) vscode. Maybe some icing like starship, a nice theme. It could be opinionated or extremely configurable (and remain stable at that over years).
Or, on second thought: I have all that. So what problem does this solve?
