Just some *very* personal opinions.
I just LOVE this iteration of XPS line
reasonable temperature and performance: it's 14nm, what could you expect? at least could maintain its performance in the cinebench loop.
nice battery life, even for a 56whr battery: it's a 45w CPU paired with a 15" 16:10 display. many laptops could only achieve similar results with a lower TDP processor. Not to mention it also have a 86whr version. It could definitely lasts you whole day, as long as you don't compile some large program or do heavy video editing, etc.
nice, big trackpad; good build quality; two so-dimm slots and two m.2 2280 slots, upgradable whenever you want; bright, relatively color accurate and uniform display...
AND IT'S 16:10!!! why isn't there more laptops adapting this? it's just better for any text processing work: coding, writing essays, even just browsing forums or IG or FB.
