> But really, imagine how much power these things have and if you could actually run a free (as in freedom, in the GNU sense) OS on them and really get access to all that power in a handheld device. Only if.

Skipping the "handheld" bit of this just for a second. You can run an (almost entirely) open stack on your hardware, and do so on an i9/9800X3D with 256GB RAM, 5080, and MultiTB of NVMe storage.

But it doesn't realy matter for 95% of users, because the hardware is already way faster than they need and the bottlenecks are on the server side and on shitty software architecture. I have an i9 with 128GB RAM for work, and Excel still takes 30+ seconds to load, Teams manages to grind the entire thing to a halt on startup, slack uses enough memory to power a spaceship... Running those apps on my desktop is pretty much the same experience as running them on my 10 year old macbook.
