For the unique part of this laptop that AFAIK a Dell XPS won't have is the Coreboot BIOS, that also probably means better support in the long term for BIOS updates.
To be clear, this is also not a laptop for me (but I did pre-order a Framework 13 Pro), but saying "nerd tax" or "anyone who buys one is either giving a donation or an idiot" like the other comment is just focusing in one part (the price) and not looking at the other.
