The latest XPS laptops really seem like they wanted to copy MacBook Pros from a few years ago with the touch function keys and the barren I/O.
I never really understood the purpose of the XPS line anyway. If you want performance, buy a Precision; if you want a light robust laptop with decent I/O, get a Latitude; if you want a MacBook, get a MacBook.
With that being said the new naming scheme sounds like a joke.
