Lots of claims in here, but no specificity. I can tell WHAT they are selling: the hardware, or a software platform.
I'm also confused because they seem to missing the mark of what a useful piece of tech is for home users. Having everything all-in-one just compounds single points of failure. Also super confusing why they're mentioning LTE and Starlink into this...makes it seem pretty stupid.
Honestly, if you're just getting started, grab a cheap refurb from the Minisforum store, get a stack started and figure out what you actually, then make more informed decisions from there.
If you're planning on hosting a large media collection, you probably want a NAS, which can also double duty for the other things you want to do as well in most cases if it supports running containers.
