well my laptop is only 1 year old so i think it will run smoothly

so it might be slower depending on your hardware

should be about as fast as kde on other distros, though iirc neon is based on Ubuntu LTS so it'll have an older linux kernel and stuff

also is kde neon fast (if u tried it)

im looking for something simple, preferrably ubuntu based but not much telemery
