It's a very robust and capable small laptop. I'm typing this to a M1 Macbook Air.
The only thing to keep in mind, is that the M1 was the first CPU in the transition from Intel CPUs (+ AMD GPUs) to Apple Silicon. The M1 was still missing a bunch of things from earlier CPUs, which Apple over time added via the M1 Pro and other CPUs. Especially the graphics part was sufficient for a small laptop, but not for much beyond. Better GPUs and media engines were developed later. Today, the M3 in a Macbook Air or the M4 in the Macbook Pro have all of that.
For me the biggest surprise was how well the M1 Macbook Air actually worked. Apple did an outstanding job in the software & hardware transition.
