Speaking as someone who just upgraded from an early 2014 MBA 11" to a Air with the M1 chip, while the old machine always felt adequate to my uses, having used the M1 for a while now, I could never ever go back.

Programs start much faster, quit much faster, web pages load much, much, much faster. Compiling is anywhere from 4x to 10x faster, as is interpreter startup time for scripts.

Now, granted, it's a jump from one architecture to another and a time span of 7 years, but this upgrade felt magical the way the mid-90s hardware upgrades felt.
