Except the XPS weighs as much as a 13” MacBook Air, has a base 1080p screen (with a battery hog 4K option), and uses 15W chips. They are nice machines, but they make their own compromises. Apple is likely going to switch to ARM, so isn’t investing significant amounts into making sweeping changes to their existing models, but the existing design was already pretty good.
Now this isn't directed solely at yourself, but this is such a bizarre mentality certain posters have on this site, as soon as you mention something another manufacturer has done better than Apple you get jumped on with a rant about how Apple is still better because xxxx - because god forbid Apple's honour is impugned on your watch =P I
know the XPS has it's own quirks eccentricities and things it falls down on, but we were
specifically talking about the design in relation to the bezels. Not the display options. Not the size of the trackpad or quality/ position of the speakers. Not the choice of CPU.
Just, you know, try to accept different machines can be better or worse in different areas without having to drag the debate around to why Apple is better.
Your point about the Arm transition is a good one, though, I hope it will allow Apple to come up with their own super svelte machines, without the compromises needed using Intel chips currently.
