(2) The first Windows tablet. Introduced when Windows XP was the current version, the Tablet PC was designed to function like a portable writing instrument. It included handwriting recognition for converting characters to text as well as the capability of storing handwritten words and annotations as images. Since the Windows XP tablet was introduced, Windows tablets have come and gone, while iPads and Android tablets eventually prevailed. However, starting with Windows 8, solid state Windows tablets finally became mainstream in contrast to their hard drive-based Tablet PC predecessors.
