I am uninterested in purchasing proprietary hardware running a proprietary operating system that'll work (maybe) for some amount of time. Sure, it's technically self hosted. But you can't extend it (without their proprietary app store). It doesn't seem like you can write your own apps without registering, or side load them. Details are extremely thin on the site, so let me know if I'm wrong.

Hell, all the compelling software isn't even theirs! They're just running other OSS apps, and god knows whether you'll be able to manage or upgrade it.

Arguably, this is the worst of all worlds: you're paying the overhead of closed hardware, running closed software that you don't control, and sort of just crossing your fingers that they don't pull the rug out from underneath you. You'd be infinitely better off buying a comparable NUC and spending an afternoon loading up Docker on it. Shit like this is genuinely insulting to the demographic of folks who should be the target audience.
