We've seen several transformer style Android tablets and a few Windows 8 models too. The Transformer Book TX300 is at the high end and it has a few features that set it apart from the Samsung ATIV 700t, Microsoft Surface Pro and Intel Atom Windows 8 tablets. The TX300 has a roomy 13.3" full HD IPS display that's easier on the eyes than 11.6" and smaller models on the market. It's the first to have an Intel Core i7 CPU and a keyboard dock with a secondary hard drive and battery. In fact, the dock looks and feels just like a Zenbook Prime Ultrabook with a backlit keyboard, a good selection of ports and Asus' signature metal casing. Remove the tablet from the dock and you've got a very and relatively light tablet with 4 gigs of RAM and a 128 gig SSD running Windows 8 64 bit. A versatile product that works equally well as a tablet and Ultrabook.
