  1. I am using Macbook M1 – 512GB version for more than 20 days now these are the pros and cons:-
    1. It’s Superfast. It will feel fast on everything – from bootup to app opening, to builds, etc.
    2. It’s slim. Air has no fan hence its form factor is even slimmer than Pro.
    3. It remains cold even during heavy code builds. It’s hard to find things which make it warm actually.
    4. I have tried several graphics-heavy games and they run great without any heat as well
    5. If you are just browsing with Wifi on, typically it loses 10% battery in 7-8 hours. But it’s for the Safari browser. It has achieved I guess what people will call power-efficiency nirvana.
    6. Screen, Sound, and Mic quality are awesome

    1. Since it winters in India now, some people might not like that it doesn’t heat up the surroundings
    2. For longer workloads – like if you are doing daily large video compressions/conversions and that takes like 15-20 minutes, then this machine will not work as fast as Pro; as that’s not the load it’s optimized for. But ask yourself – whether you are gonna do that at all.
    3. Camera is 720p and that sucks about every other laptop as well. But Apple has brought some software optimizations which will make it look better
    4. It doesn’t make the sound of a fan, so you might feel asleep if you are used to that to keep track of your ML jobs.
