I am working since one year with the last XPS 13, the lower priced version and it is a very good notebook for developers imho, I might would buy it again. Only might because Dell sold the last model including quite a few bugs (Sound and Keyboard didn't work). Before you could work with it you had to upgrade the bios and the OS. Considering the amount of time required for this it was expensive. Dell did know about the problems but sold it anyway. I sweared I will never buy a Dell again, but then there aren't too many other options left anymore.
