This is how opinions differ. IMO plastic is better than aluminium. It is robust (if done right), lighter and doesn't have good thermal conductivity (which makes laptop usage possible, MacBooks can be uncomfortable for lap usage if too hot).

The metal is more "luxury", though.

This was definitely the case in the Intel era, but I can't say I've had this problem since the move to Apple silicon

I have an Air. Maybe active cooling prevents it from getting too hot. With the Air, the metal body is kind of the heatsink.

I can configure my Snapdragon plastic laptop such that the fan doesn't turn on, so the body being metal isn't a requirement for not turning on the fan...

If the body was a heatsink, it would be extremely hot to the touch.

From your link:

Essentially the bottom cover of the MacBook Air becomes one large heatsink

Anyway, the author claims:

you are the type that likes to work with the MacBook Air on your lap it will be quite a bit more toasty than before.

Does toasty mean extremely hot?

The Apple M4 CPU is, if I recall correctly, capable of converting 20 watts of electrical energy in to heat, at full throttle.

Is that likely to bring the back plate or a MBA above 45 degrees?

You’re probably right, with sustained workloads it could.

Everything’s a trade off.

In a Notebookcheck test, they got the bottom plate up to 43C, and top plate near the screen up to 45C: https://www.notebookcheck.net/The-passively-cooled-M4-SoC-ma...

My body is the heatsink

Also for males it is natural birth control. Can be a plus depending on your situation

Don't all macbooks have one?

Makes me wonder if this is an ADA requirement for education devices. (assistive listening devices)

Not even ADA - kids all get headphones to listen to education materials. Wired headphones are way, way easier to manage.

There’s also plenty of room for it which is why it continues to appear on all MacBooks.

This isn't news, all MacBooks have one.

Yep. I miss my plastic phones too.

I'd go further and suggest that metal is a lousy substance for laptop enclosures.

Plastic is better if done right. I do not know a single manufacturer today which does plastic right.
