Asus already has a similar product on the market, the Eee Pad Transformer, with a dual-core Nvidia Tegra 2 processor, and its signature feature is a detachable keyboard that can make the tablet look more like a laptop. It's not clear if the keyboard module for the Eee Pad Transformer will work with the new model.
It seems likely the new Transformer will come with Ice Cream Sandwich, version 4.0 of Google's Android operating system for mobile devices. Android 3.x, aka Honeycomb, was a stopgap measure intended to help Android tablets reach the market as soon as possible, but Ice Cream Sandwich is a more finished product and won't be out of sync with the OS version running on Android phones. Shih said Ice Cream Sandwich could arrive on tablets "maybe earlier" than the end of the year.
Asus has set high expectations for its tablet family, predicting earlier this year that Asus would out-ship all other tablet makers except Apple. Asus also offered a tease video of the Transformer Prime yesterday. It showed a close-up view of the keyboard, including a USB port, and the combination screen and tablet detaching from it.
Nvidia already powers most Android tablets today, and it seems likely that its new quad-core Tegra 3 chip will be a prime selling point as Android tablet makers strive to compete with Apple's incumbent iPad.
