Dell XPS 15

Pros: Looks good.
Fast.

Cons: Defective WiFi that's on all the XPS laptops.
Horrible viewing angles for screen.
Gridline pattern on screen that's supposed to separate pixels.
Fan is incredibly loud.
Laptop gets hotter than most others of the same quality.

Summary: I am an engineering student who needed a laptop that was powerful and had a reasonable price. I recently purchased this laptop and found out very soon that the Wi-Fi did not work well on this laptop and was horribly defective.
As I did my research, I can see this is a problem for a lot of people. It's a problem for FAR too many people. It's not just an issue with the XPS 15, it's an issue with the entire XPS line on laptops.
When I spend $1,700 on a supposedly high end laptop to do my work and study, I expect to get what I paid for, and I'm sure others feel the same.

As an engineering student, I can say that the Dell engineers are failing to do what they were hired to do. This Wi-Fi problem has been an issue for MONTHS, yet they still ship this product and have no warning to potential buyers when Dell is aware, and have directly acknowledged that this is an issue. You must understand that this company has attempted to address this issue with external Wi-Fi receivers, BIOS updates, driver updates, etc., and the company still has yet to fix many of the units they've shipped. Dell apparently isn't even bothering to look at the engineering of the Wi-Fi receiver, because keep in mind that this is the only computer in the market that seems to have this "mystery" Wi-Fi issue.

I'll say the pros of this laptop are design, speed, and pretty good specs for the price. However the faulty Wi-Fi negates all of this.
I also want to not that the screen has very bad viewing angles, which is disappointing considering may IPS monitors are widely used on other computers with perfect viewing angles, yet Dell still uses TP monitors. Not only are the viewing angles poor, there's a faint grid pattern on the screen that is supposed to divide the pixels.
I would have been better off with a desktop at this price. The fan noise is an issue as well and can hardly use it in class without distraction.

I'm highly disappointed and discourage anyone from buying this laptop, or any XPS laptop. More so at the fact that Dell has known the Wi-Fi was faulty for months yet has done nothing about it and still ships the product. None of Dell's solutions work; I have been through the pain of tech support. Their "solutions" have not worked for many other people.

You will, in all honesty, be better off with an Acer, Asus, or Lenovo computer. Dell has ruined their company name with this product. Frankly this needs to go to court and Dell needs a lawsuit against them for even shipping this product without a warning of an acknowledged issue, and I'll be happy to take this to court.
