AnandTech - ASUS' Zenbook Prime is due for its official launch later this month. As we found in our early review of the UX21A, ASUS addressed nearly every problem we had with the original Zenbook. While Ultrabooks won't really get super exciting until Haswell, if you've been holding out for a non-Apple ultraportable, the Zenbook Prime is likely just what you've been waiting for.
Pocket-Lint: The term Ultrabook has become so loose now that just about everything which isn’t made by Apple and is portable has the moniker slapped on it. The problem is that a lot of the kit released just doesn’t cut it, with most being far from ultra.
Tek Syndicate: We've been having some fun with the new Asus Zenbook UX32VD-DB71. Wendell and I did a full teardown. We were mainly doing this to replace the HDD. The 5400 RPM drive just doesn't cut it. Must have SSD speeds! With the OCZ Vertex 3 Max IPOS it freaking screams.
Engadget - We've already seen spec sheets suggesting that ASUS's 11.6-inch and 13.3-inch Zenbooks are being fattened up for a major update, but now Engadget Chinese has glimpsed the new devices in their cold aluminum flesh. Tentatively called Zenbook Primes, or the UX21A and UX31A respectively, they both have 1920 x 1080 IPS panels with a matte finish and excellent viewing angles (please, ignore the dumb 1024 x 768 screen-saver in the pic, it doesn't do it justice).
