I use Dell XPS (2015) 4k model with Linux installed. I'm super happy with the laptop so far. I bought a refurbished i7 model when I was student, it still is the best laptop investment I've made so far. The issues I've had with it: 1. I had to change my power adapter twice. I dunno why it has such low life. But an original new one is just costs around $20. 2. Since, it was non-developer edition came with broadcom wifi card, I switched it to Intel which has much better Linux drivers IMO. I think they now use some "Killers" wifi module. I've no idea how they are. 3. After 3 years, it stopped charging because the power socket was damaged. I think it wasn't unexpected because of my rough use, and often bending the cable there. I got it fixed for around $130. In hindsight, it probably wasn't hard thing to fix, as long as I can get the part from eBay. 4. After 3.5 years, the battery life got really bad (like < 2 hours on 4k). I bought an original battery from eBay and replacing it was pretty easy. Now I think I get like 7 hrs on 1080p, and maybe little less than 5 on 4k. 5. Using 4k resolution on GNOME is kind of laggy. I think its mostly software issue than hardware. Unity used to work great, and I think Windows was smooth too. The body is still solid, and I think I can use it for another couple years for all my development needs. I really like the carbon fiber finish. Its usually pretty warm and comfortable (when you first open it), unlike aluminium bodies which gets chilly.
