The only place where the XPS 13 is inferior in terms of build quality, so far as I can tell, is coil whine. I believe they've fixed that in the most recent versions.
Also, even though it's not a big deal I'd rather not have a touch screen at all as I do on the XPS. It's useless, and registers touches when I close the lid (I prefer not to suspend if I'm just walking from one room to another)
Edit: I should note I use Ubuntu exclusively on the XPS 13. I don't know what the trackpad is like in Windows. Presumably it's comparable.
Also my XPS13 is 2 years old and the "carbon fiber" cover started to disintegrate along the edges. The screen hinge is a bit loose so it wobbles a bit with movement.
Other than that it's fab :)
