Seconded. I have a 9360 and I've had everything work out of the box with Ubuntu 17.04, 17.10,and 18.04. As well as Linux Mint 18.3.

Only downsides are Linux's generally patchy support for hidpi, some programs scale and others don't (opt for 1080p version or set resolution to 1080p). And also the placement of the webcam is a bit strange.

Battery life is good in Ubuntu, between 6 and 10 hours depending on use case.

This is third degree price discrimination by Dell. I should have been more precise in my first comment.

To be crystal clear: the 9360 has a bios featuring the proper ACPI tables, which are omitted on purpose from other cheaper models, breaking S3 on purpose.

This is why injecting proper tables as proposed in this link restores normal functionality. It is not rocket science, just hard enough to do without proper documentation to be a waste of time.

The initial submission title said it was a shame, and I agree it is shameful to intentionally break features to charge higher price (and no, I won't buy that S0 works perfectly now, or that adding a simple if/else is "too complicated"

With cheaper models you mean non-XPS-13 models?

non developper models
