> 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.
> slack uses enough memory to power a spaceship...
Which spaceship though? Not sure spaceship is the model you're looking for, as all of the ones I'm familiar have had a very locked down limited amount of memory. Apollo had something like 4Kb of memory. The space shuttle had 1MB.
Something seems to be funny with your computer's setup. On my feeble i5 laptop with 16GB, Excel starts in about 3 seconds to the point where I can start doing stuff.
If it's a corporate device, it's usually some anti-virus abomination (or other security-related software) that steals 90% of the resources.
