The new ASUS Zenbook Prime (UX21A 11"/UX31A 13") models that were announced last month have similar specs to the new MBA (Ivy Bridge, up to 256Gb SSD, etc.) but are both available with 1920x1080 IPS screens. I had the original UX21 and sold it because the keyboard was not so great, but from the reviews of the new models, they have improved the keyboard and trackpad.
