I have the non-developer version of the laptop. Imho the only thing that really differs is the network card. And in the XPS, you can replace your network card.

I have the non-developer version of the laptop. Imho the only thing that really differs is the network card. And in the XPS, you can replace your network card. Having said that , I have the non developer version and have had out of the box experience. In fact, it has been a long time since I saw network problems on any laptop for a long time. The biggest issues you will see are around secure boot and UEFI configuration. Dell has an excellent BIOS that takes care of this.
