Cinnamon is the only other desktop environment that I can really use besides KDE. To me they’re equal in quality. Cinnamon does some things better than KDE, KDE does some things better than Cinnamon. It varies based on how each one is configured in your distro’s repository more than anything. KDE on Arch is top notch. Cinnamon on Arch is hot garbage. Cinnamon on Ubuntu is usually really good, KDE on Ubuntu was barely usable last time I tried it.
If you know a lot about desktop environments you could fix either one yourself but I only use them based on which one works better after I download it and configure basic settings.
It’ll happen some day. There will eventually be “Illegal” wireless transmitting devices that do things such as transmit data over disallowed frequencies, break the token rate speed limit imposed by the fcc (fuck 56k) and illegally use encryption (using data encryption on amateur radio is illegal). When they do start becoming a thing, they’ll be able to transmit data maybe a few miles at up to a megabyte per second (not 1 megabit), or for dozens of miles at a few kilobytes per second. Depending on whether the designers wanted to prioritize speed or distance.
The technology exists to make such wireless transceivers using off the shelf parts available to normal people, there’s just no reason for them to exist. Yet.
