In pictures: Sony's S1 and S2 Android tablets

Sony will make its long-awaited entry into the tablet PC market later this year with two models based on the latest version of Google's Android operating system. The tablets, which carry the development names S1 and S2, will be launched worldwide from the fall, Sony said on Tuesday. 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.
