The Dell site is absolutely terrible. For a while, perhaps still, there was no way to show the tech specs for at least the XPS laptop I was looking at. The marketing speak would say something like "XPS 13 with 6th Generation Intel Core processors" and then just a series of prices. You couldn't tell what CPU it had, how much memory, nothing. There's a Q/A box on the page, and there were dozens of unanswered questions like "how big is the hard drive" with no answers.
I bought my XPS 13 from Costco, which was a nicer experience in pretty much every way.
