Motorola's WiFi only variant of the Xoom has been spotted at the online retailer B&H for $599 on pre-order. The B&H ad is the first we've seen that offers pre-orders on the Xoom on immediately. That may satisfy your need to lay down the plastic, but patience can be a virtue. We noted last month of Sam's Club's plan to sell the Android 3 (Honeycomb) tablet starting March 27th for $539 (membership required). But if you really want it now, there's always the 3G version on sale at Sam's for $599 on a two year contract.
