Tablet PC combines the incarnation of previous notebook computing technologies (such as digital ink and voice commands) with the power and reliability of Windows XP. This platform (based on Windows XP and compatible with any Windows application) also provides opportunities for programmers and developers. Microsoft released a free Software Development Kit (SDK) for the platform, allowing programmers to take advantage of the new functionality and this text teaches how to create applications for this platform using the SDK. It begins by explaining how to install and use the SDK, and then delves into the creation of several specific applications, such as a drawing program, an MP3 player and a speech and signature recognition program. It also covers some game related topics.
