I have tried arm computers such as raspberry pi and they are slow. The linux arm projects seem to target just the cheapest price, m1 seems more like bang for buck. I hope linux hardware develops towards that.
the arm chromebooks like the lenovo duet absolutely murder the iPad pro or even the new iPad Air in terms of actually being a useful OS for devs
as an ex macbook pro main, I bought 3 of them over the course of last decade and a half and they have always had older intel brains than any xps or razer stealth I would try to cross shop with. after m1 apples price to performance ratio is at unreal levels
