The company didn't announce pricing details or specific launch dates, but it did offer some basic specifications and demonstrate prototypes of the two machines at a Tokyo news conference.

The S1 is a slate design and has a 9.4-inch screen. At first glance it looks similar to most competing tablets, but look more closely at its profile and you'll see it's shaped like a wedge. The upper portion of the tablet is thicker than the lower portion and that makes it easier to hold, said Sony.
