That screen, oh, that screen...
It's like the device was hamstrung at birth: give it good software, but slap it into a line (XPS or Inspiron) that has a short shelf life and hobble it with a low-resolution screen and sell it for more money. I can see why (those panels are cheap and it keeps costs down) but it's an unfortunate choice. You might as well opt for their 12" flip-book and hope.
It would be nicer, I think, to see a Latitude with 1920x1080 or 1200. Mind you, Dell (nor Lenovo, with the T-Series) doesn't have a high-res Latitude that isn't a 15" brick. Or get a MacBook...
