The first release of Transformer Prime is on the way into the U.S. partner stores and more will be available and shipped as and when possible over the next few weeks as confirmed by a spokesperson for ASUS.

The prime tablet is available on sale on BestBuy at $499, though it appears that you can only order the exclusive Gray model currently. Also various models are available at a price on Amazon, with other pre-order models looking at some 4-6 weeks delivery wait.

Jonney Shih, ASUS CEO, has said that the new model and tablet PCs, in general, are expected to sell upward of three million tablet PCs in 2012 with a hope that they may sell six million if things go well.

Running on Android 3.2 Honeycomb, it has the advantage of running a version of Android that was made especially for tablets along with a powerful NVIDIA Tegra 3 quad-core processor. Tegra 3 is based on ARM architecture CPU and designed to deliver exceptional graphics on mobile and handheld devices.

It is the thinnest tablet on the market. In addition to its sleek looks and affordable pricing, it also has an intelligent design. The Prime is a device of two halves: a 10.1-inch tablet and a keyboard for it to dock into. It has been seen to be a good option for users who need a laptop and also want a tablet. The estimated battery life is 18 hours.

Meanwhile, Hasbro has sued Asus over the name of its Transformer Prime tablet last week in a federal district court. Hasbro has sued Asus for trademark infringement, unfair competition and trademark dilution. However, ASUS has confirmed that production of the Transformer Prime tablet will continue and not be affected by this trademark infringement lawsuit.
