March 27 is a big day for anyone in the US waiting for the contract-free Wi-Fi only version of the Motorola Xoom Honeycomb tablet. Said to be available for US$600 in Amazon, Best Buy, Costco, RadioShack, Sam's Club, Staples and Walmart, the Xoom eschews the 3G and 4G components of the Verizon version but will still have all the same specs like the 1GHz NVIDIA Tegra 2 processor, 1GB of RAM, 32GB of storage, a 5 megapixel autofocus camera, and a 10.1-inch display with 1280 x 800 resolution.
