> Paying for an unused Windows license for the XPS was unavoidable
The website gives you the option to save $90 if you have them install linux on the XPS 13. I suspect you may be able to call and get the same deal on the XPS 15. At least when I was buying from them 20 years ago you could do that...
AFAIK XPS 15 doesn't come with a Linux option (and for me, I bought it through a reseller who had a black Friday deal, so I wouldn't have had the option).
That's correct, you may in fact order an XPS 13 pre-installed with Ubuntu from Dell. But you won't find an XPS 15 model with that option. I couldn't find it in January when I went to buy mine.
