There is no further news though as to what the tablet would cost or from when the S1 will start shipping. However, as for the latter, it is expected to be around mid September when the Sony tablet is expected to reach stores. This is also in line with the previous reports that we have heard of the Sony tablet that are expected to make a debut towards fall.
