Asus is today introducing the TF700T, a new variant of its Eee Pad Transformer Prime tablet, whose major upgrade is a move to a 1920 x 1200 resolution. That makes two Android tablets moving to a 1080p res at CES 2012, following Acer's unveiling of the Iconia Tab A700 yesterday.

The new Transformer Prime isn't sacrificing quality for quantity with its move to a much higher pixel density — its display is still made of the SuperIPS+ stuff that impressed us so much when reviewing the TF201. Another highly significant upgrade is in the tablet's rear cover design, which has been altered to allow for better GPS, Wi-Fi, and Bluetooth performance. Great for new buyers, to be sure, but we wonder how happy owners of the current-gen Prime will be with this news.

Android 4.01 will be the shipping OS on the Transformer Prime TF700T, which should cost between $599 and $699 when it hits North American shelves in the second quarter of 2012. Compatibility with the TF201's keyboard dock is retained, as are most of the internal components, including the 1.3GHz quad-core Tegra 3 system-on-chip. Onboard storage on the new Prime will be either 32GB or 64GB, depending on your preference. The only other notable step-up for the slate is in the front-facing camera, which has been upgraded from 1.2 to 2 megapixels.
