This has not been my experience with my FW16. I also have an XPS for work, and had a Gigabyte Aero before that, but I would hands down take the the FW16 over the XPS 9510. While the XPS doesn’t have any major issues running Linux (though I am unhappy with the trackpad), I haven’t had any issues running Linux on the FW16 either, and I absolutely love having whatever ports I want available. I really missed the great port selection I had on the Aero, which made the XPS painful for me to use (I am so sick of dongles). I use my FW16 for a bunch of different requirements and have a ton of ports for it: ( 4x Ethernet, 3x USB-A, 3x USB-C, 2x HDMI, 2x DP, 2x MicroSD, 2x 3.5mm). Being able to reconfigure on the fly for whatever my workflow is for the day has been great.
Also, something that really galls me about working on the XPS series vs. the Latitude series, is that even though the XPS is supposed to be the premium line, the Latitudes are much nicer to work on. For example, Latitudes have captive screws on the back cover whereas the XPSes don’t, and they also have razor sharp un-polished edges on the covers (always great to have to clean the blood off your motherboard traces before you can power it back on. )
As for the display issues, I can’t speak to that because I use Hyprland and don’t have a DE, but don’t see any issues.
If they don’t have to worry about guns, then why do they have guns drawn?
