Thinkpad X220 has 500 times better keyboard than X.

I use daily both an MacBook Air m1 and x220. I have the 9 cell for the x220 and run Linux on it. Battery life for the most work (I do) is similar on both.

There are some interesting cases; running Docker drains the m1 (only ARM images) faster than the x220 and doing typescript work drains the x220 faster than the m1.

Afaik on Mac OS Docker starts up a large Linux VM and has that run the containers, while on Linux it uses the base OS for that. x86 or arm, it's the same. That explains the extra battery usage (and RAM) on Mac OS vs Linux.

Battery life can be measured and compared more objectively.

And when it's all you got, point it out often!

I kid. I use a Mac for work and it's okay. I prefer Linux, but it is what it is.

Yes and so can how thin a device is. So here we are.

A dead battery is more of an issue than varying levels of thinness.

Battery life, for a portable device, is probably the most important metric.
