Dell is offering some considerable discounts across its XPS 13 range at the moment. Some of the deals are time limited, so if you're in the hunt for a handy-sized Ultrabook that can offer great performance with a small footprint, now is the time to act. Over US$400 can be saved on some SKUs.

I have a dell XPS 13, it has many issues with bios and drivers, even after 3 years of releasing updates dell has still not addressed all the issues, I can't recommend any XPS 13 until dell stops releasing hardware prematurely.
