Cooling is sub-par, but I think that's mostly due to the Intel i9-8950HK running way over the advertised TDP during Turbo. Dell has been tweaking their cooling profile in subsequent BIOS updates, at with the latest version (1.15) they're quite aggressive on ramping up the fans to keep things cool. Which is good from a performance perspective, but really annoying to sit beside all day. While I didn't experience severe thermal throttling, I did end up disabling Turbo as it made the laptop sound like a jet engine too often for my taste.
My only other complaint would be that despite Dell's claims of 100W+ power delivery from their ThunderBolt dock (above and beyond what USB-C PD can deliver), I frequently find the laptop discharging the battery under moderate load (high CPU, idle dGPU) when connected via USB-C to the dock. Using the supplied DC charger solves this, but it's still a poor user experience.
At my previous employer I had a 2017 MBP. IMHO an XPS/Precision is a better option as you can (in no particular order): upgrade the RAM, upgrade the SSD, run Linux on it, and (until the new MBP release) had a much better keyboard experience.
As others have noted, Dell's enterprise warranty support is fantastic. I was able to invoke the warranty to replace a motherboard in a Latitude I bought used on eBay; they sent a technician to my house to replace it free of charge.
I bought a macbook and use the dell charger (udb-c) to charge my macbook.
Okay, I thought. $200, maybe $300, including parts and labor.
Not quite. They wanted $879. "Maybe we should look at getting you into a new Macbook instead?"
No thanks. It was almost never used unplugged anyway.
600 is pricey for a mainboard replacement, but none of the other vendors are much better, including Apple. I previously had a Thinkpad that died shortly out of warranty, and they actually wanted more to fix it than I paid for it new.
on any intensive work it would get so hot that i could not rest my hands on it.
What followed was a year of fan noise, thermal throttling, GPU switching problems and many hours lost trying to get the right combination of Ubutunu + Nvida drivers working.
So when my house was burgled and that machine got stolen, I went back to the XPS13 form factor. Smaller, lighter, longer battery life, quieter. Only disadvantage being the max of 16GB RAM.
Once the XPS13 finally arrives with 32GB RAM I may well upgrade again.
The new MacBook Pro may tempt me, but I am certainly not giving up proper function keys.
If you live in a city with good Dell support, you could probably have managed to replace it. Sounds like a hardware problem.
Things went downhill rather quickly. I've had massive cooling issues, I've removed and replaced the thermal paste. I've been forced to operate the laptop on the "Cool" thermal setting; downgrading the performance of the processor. Now, the two of the screws in palm rest, which hold the screen in place, have sheered right off. Doing some digging, this was commonplace with this particular model.
I'm not doing anything particularly intense either. Docker with a few containers running a dev website.
I can't speak for the latest XPS 15 7590 build quality however.
