My current options look like:
1. Asus Zenbook (13 or 15.6")
2. Dell XPS (13 or 15.6")
3. Lenovo X1 Carbon 14"
The Asus is the best value even though it is over specified with i7 and 16GB of RAM and touchscreen for $1499. It does have a 3840 x 2160 IPS screen, Thunderbolt 3, USB 3, Dual-band 2x2 802.11ac, Bluetooth, SD reader, Nvidia GeForce 960M GPU.
