I bought the new MacBook Air m1 less than 2 weeks ago and it's running Big Sur. I have been using a digitizer for e-class and sometimes it freezes, which isn't what I expected from a 1200 euro laptop. If it is unable to handle something like that, then it's just a big waste of money. I am not going to start using apps for cleaning apps working in the background, which is hopeless for such an expensive piece of equipment. Also the function key which switches languages stops working after a few times to the point I had to switch it to caps lock. Skype's share screen function just stopped working without me changing anything, to the point that I had to switch back to my old windows laptop for work. I bought a MacBook over a windows laptop with the hope that I get a better working environment and it turns out that it's worse than my 10yo laptop. I hope the OS gets fixed soon because I don't want to see such an expensive investment, in our times, to be used just for browsing and watching movies. All in all Im very disappointed from the first 2 weeks of use.
