Why not Linux?

Worse battery life. Really though, the applications you need should dictate the OS you use. If Linux works for you, by all means, use it.

I didn't downvote you, but even my Macbook friends were jealous of my 20+ hours on a Thinkpad x250 (9-cell).

The default power settings on Linux are pretty bad, though. Anyone with Linux on their laptop should create a boot service that runs this command:

    powertop --auto-tune

...and observe battery time increase by ~25%.
