Asus Transformer Prime pre-orders start on BestBuy for 499 USD

The next most powerful Android device on earth is now available for pre-order from Best Buy, that being the Asus Transformer Prime, an NVIDIA Tegra 3 quad-core processor toting 10.1-inch Honeycomb tablet.

This device is available for pre order in two forms: one with a gray back, the other with a champagne back. Both models have 32GB of data storage built-in with a microSD card slot to expand by an additional 32GB if you wish. They have also got the official champagne-colored keyboard dock and a mystery portable dock which we must assume is the gray-colored keyboard dock, both up for 149.99 USD and at pre-order status as well.
