Sony in the US has started accepting pre-orders of their amazing Android tablet dubbed as the Sony Xperia Tablet Z. The device is being offered at $599.99 and that is the 32GB WiFi-only variant of the tablet. For those who are in the US and wants to pre-order one, then head over at Sony's online store now. Sony estimates that they will be shipping the first stock of the Xperia Z Tablet come May 24th. By the way, Sony is throwing in the device's cradle which, I believe will be included in the $599.99 price. This is a great deal, if you ask me.
