This is best told as a short story- In the late summer of 2018 myself and another tech rep were in California at a chemical plant. After just 1 1/2 weeks our rental car was broken into and computers stolen! The plant offered to replace my machine and asked me to tell them what I wanted. Not having much access to the outside world at the time but having recently reviewed some Dell ads for the XLS I told them a Dell XPS-15 as It looked like it would be what I needed (a nice large high res screen and good overall specs), this was a big mistake. As I needed to multi-boot (which I have done on my self-assembled office machine) I later found out that the I5 Intel chip and likely the BIOS itself prevented me from loading a second op system (incomplete and deceptive specs.) At that point the computer was useless to me (this was after numerous call to marginal tech support where this was finally revealed.) The reason for the need to multi-boot was that a necessary piece of expensive software will not load in Windows 10 (thanks, Microsoft) and I needed to install Win7 to run it. Also, the stolen machine was a Toshiba that had a switch on the side that would turn Wi-Fi on/off so I was comfortable with Win 7, not so with all the newer machines (I guess spying on the users is more important ?). This can't be just to save $5.00 on a switch. This is not to mention the average 30 min boot-up time! I recently wiped the machine and re-installed from the start-up menu (safe mode) and voila the boot time is now much shorter and closer to what one would expect, this took over 6 hours to accomplish. It seems that pre-shipment factory checks are non-existent. I also experienced several apparent hard drive failures, but it wasn't the drive, it was the SATA connector. The ultra-short "cable" put a side force on the drive end. This happened three times but not since I don't travel with it anymore. Last but not least, about 2 months after the hardware warranty expired the leftmost hinge failed (most mfgrs fixed these problems around the mid-aughts). The only thing I use this Expensive computer for now is Zoom Chair Yoga every Thursday.
