I'm looking forward to a real XPS 15 7590 review. Dell absolutely has a track record for getting key things wrong and they're often seemingly oblivious or simply don't care about some of the problems. I think if Microsoft wants to buy 15,000 of a given model laptop they listen. But if they have unhappy individual users they generally don't care unless the complaints reach some obvious critical mass. People need to bash Dell in a big way when they get things wrong but online reviewers getting free samples rarely do.
The sad thing is Dell clearly has the resources and expertise to make no-excuses excellent products. But, for whatever reason, they often miss the mark in at least a few critical ways. It might be a serious thermal issue, a horrible trackpad, incredibly annoying fan management, wake from sleep issues, WiFi issues, etc. So I couldn't agree more we need in-depth reviews that expose the sorts of flaws that are not obvious in a quick evaluation at a show, in a retail store, or even a quick unboxing.
The XPS 15 is in an increasingly rare product niche. Most of the competing 15 inch laptops are either inferior in significant ways or have their own hard-to-live-with flaws. The LG Gram 15, for example, has the trackpad stupidly offset from the keyboard. It's the sort of dumb mistake not even Dell would make. It's a very Apple-like form over function choice where some idiot at LG decided the trackpad needs to be centered on the chassis for aesthetic reasons not on the keyboard with it's numeric keypad creating a huge offset. A quick summary of the specs doesn't tell the story of daily usability. You have to live with it for a while.
