I love my MacBook Air 15" M3 so much. It is large fast and light. While I really appreciate the improved M5, my main ask is actually a brighter screen. The current 500 nits is a bit low if you are ever not in a dark room.
Anyhow, because the differences between my M3 and the new M5 are just the CPU/GPU and I am not actually hurt much by the current CPU speed, I won't be upgrading.
