It's everything I wanted from the one Dell XPS 13 that I previously owned and more, with the exception of speakers that are unsuited to quality music.
The battery life is fantastic, it's light weight, thin, larger screen (I ended up hating 13 inches). It's absolutely cool under pressure- just as fast as my last MBP at compiling code, but it doesn't sound like a helicopter is going to take off (tbh I forget if it even has fans, but if it does I've never heard them).
I went through the trouble of booting / windows and grabbing the latest firmware updates before installing linux, but literally everything Just Works. Close the laptop lid and there's practically zero battery drain overnight.
If games are your thing, you're more or less stuck at casual gaming, but it's easily become the favorite laptop that I've owned across HP, Dell, Apple, Acer and Toshiba.
The only downside I can think of is that people other than me tend to hate 10+ keyboards, but I'm used to it and it doesn't bother my wrists at all (plus I get a number pad for quick entry!)
