Most everything I've seen around the M1 chip come across hacker-news (can't watch Linus Tech Tips and not get annoyed by his O-face anymore) say it's heavily software dependent, which great, macos supports, linux if/when supported probably won't, but as usually apple optimizes their os around their hardware quite specifically. Some testing of windoze arm has even said it runs better on M1 hardware than microsoft arm surface hardware too, so who knows, but I suspect raw linux would run like ass if/when getting to work finally. If more arm vendors follow suit, perhaps, but until then apple hardware will be another walled garden beholden to their os alone.
I've looked for years to get some hardware such as a tablet or other thin-ish hardware device to be a go-between between my human interface and my hardware systems, but I've never found a substitute for just being able to run different OS's and things on hardware as slim as my laptops. Android tablets are mostly useless, ipads marginally better, but still nothing replaces a native hardware pc solution, where simply I need cpu+memory+disk, and lots of it. I'll never get that from arm boxes I think.
My next laptop will likely be a ryzen/threadripper setup and a real gpu. Intel+nvidia with prime has been an abortion from go some 10 years ago, can't get worse, but buying an 8/16gb fixed (ie. soldered memory) mac with an arm proc/gpu will likely never satiate my need even in a laptop with constantly running separate windows/linux vm's constantly. Something I'd give to a 10 year old or my grandmother to play bejewelled, fakebook, and tweet with twits, sure.
