The latest, cost-effective rumor surrounding the Wi-Fi Motorola XOOM is sure to pique the interest of the few penny-pinching readers. Blog Droid-Life is reporting that Sam’s Club (of all places) will be selling the Wi-Fi XOOM for a cool $539. This undercuts the $599 price tag Motorola Mobility’s CEO, Sanjay Jha, slapped on the device just two weeks ago. A 10.1-inch Honeycomb tablet with 32GB of storage, and host of other high-end features, sounds pretty good to us –Â especially at $539. Thoughts?
