According to the specs, this laptop is actually only 1.3kg and 15.8mm thick.
As a couple of comparisons, the XPS 13 is 1.27kg and 14.8mm thick; the MBP 13 is 1.4kg and 1.56mm thick; the ThinkPad X1 Nano is 1.18kg and 13.87mm thick.
Note you have to compromise with the X1 Nano, as it maxes out at only 16GB of RAM, and doesn't have great battery life.
So this is lighter than an MBP, and basically the same thickness, all while being upgradable - you haven't convinced me that this isn't witchcraft ;)
