Microsoft is planning to make the software development kit (SDK) for the new version of the touch-centric Surface 2.0 system available for download on July 12. The Surface 2.0, which is being manufactured and distributed via Samsung (and is officially known as the SUR40), is expected to be priced at around $7,600 when it debuts later this year. The Surface 2.0 is expected to be thinner, cheaper and more versatile (able to be used horizontally or vertically) than the Surface 1.0 tabletop computer. At Mix ‘11 in April, Microsoft officials described the coming SDK as enabling developers to create “write once, touch anywhere” applications. They said the new SDK will allow programmers to create applications targeting both touch-enabled Windows 7 PCs and Surface 2.0 systems,
