'Adobe® Reader® is the free, trusted leader for reliably viewing and interacting with PDF documents across platforms and devices. Adobe Reader Touch has been specially designed for the new Windows 8 Touch user interface to give you a great experience working with PDF documents on your Windows 8 Tablet. Adobe Reader Touch works with a keyboard and mouse, but desktop users with keyboard and mouse may prefer to install and use Adobe Reader XI.
