I've been disappointed in general with the XPS line in recent years. Dell has made some keyboard changes that I am not a fan of:
A touch bar instead of function keys? Why? Did they not learn from Apple's mistake?
Changing Fn + Left to Page Down instead Home? And Fn + Right to Page Up instead of End? Once again, why?
I've been purchasing the XPS line of laptops since 2013, but I stopped as soon as those changes landed and the Developer Edition of their laptops shipped with inferior hardware compared to the Windows ones.
