Best Ultrabook with Thunderbolt?

So Computex is going on and all.. but what do you guys suggest? One of these new ultrabooks (the Acer looks quite nice), or the refreshed Macbook Air (with possibly a "retina" display).

Here's the dream:


High performance, high Capacity SSD

4+ GBs of RAM

Ivy Bridge

Touch Screen optional

Amazing battery

Great assortment of ports, but Thunderbolt a must to get a dock for "office use" (discrete GPU, bigger monitor, ethernet, etc).
