The newer Dell XPS 13s are really nice. They're a great dev laptop.

If you want something with better graphics, I'd suggest one of the MSI gaming series:

Came here to say this. Have the XPS 13, and have been very happy with it. However, wishing I would have go the 15 as a small footprint is less of a concern than I thought it would be, and I'd appreciate more screen RE.
