I have had the opposite experience. Switched from a MB Pro that kept getting progressively worse over the course of a year (keys giving, overheating, lock ups) requiring rather annoying applecare interactions to an XPS 15. Granted it is not quite as pretty look at, but blows the mbpro out of the water performance and stability wise.
