The performance seems great in comparison. But this laptop seems a bit thin for my taste. There would be room to almost double the battery if the thickness was increased. There would also be room for USB-A and a LAN port. Two things I would really like to see.

Also I read a lot of bad experiences here on HN with the XPS line every time it comes up. Personally I know at least two people who had a bad experience with it and ended up replacing the machine with something else. Is Dell improving on that part or has it stabilized?

On paper the machine looks really good but right now I just can't justify pulling the trigger to replace a Retina-MBP.
