The XPS13 2015 is the same size as the Macbook Air 11". It has a screen the size and battery capacity of a Macbook Air 13", and the two screen options are both higher resolution than Apple offers, never mind having touch input as well.
Let's compare sizes:
MBP13: 325 x 227 x 24.1 mm, 2.06 kg
MBA13: 325 x 227 x 17 mm, 1.35 kg
MBA11: 299.5 x 192 x 17 mm, 1.08 kg
XPS13 2015: 304 x 200 x 20.7 mm 1.18 kg, or 1.27 kg with a 4K/touch screen
Why would you go for the MBA13 when it is bigger, with a lower specc'd screen, gets the same battery life, and costs the same, if you were just going to install Windows/Linux on it? The MBA11 has an 11" screen and only 2/3 the battery life of the XPS. And the MBP doesn't even come in the same form factor as the XPS13...
