MacBook Air m4 will be launch or not
So far no leaks about it bro. buts its due for an upgrade. apple upgraded only the default RAM to 16GB on all existing M2 and M3 macbook air. so may be it could be delayed a bit. if its not urgent you can wait for m4 release.
If you need a computer to use right now, then you may go with current models bro.
there will 20% difference in performance between m3 to m4. so we have to decide based on the urgency right now.
