From International Data Corporation (IDC):
A customizable research access application developed by the leading global market intelligence and IT advisory firm. The IDC Research Reader optimizes the ability for IDC clients and registered users to find and consume their most recent research, as well as personalize and easily browse multiple categories of content. The IDC Research Reader gives you access to the world's largest repository of technology and industry market research data and advice. A valuable feature of the IDC Research Reader is that it enables you to create custom "Content Sliders" within the application. These "Content Sliders" allow you to immediately view the new content most relevant to you. Download content and read it when and wherever you want without connecting to the Internet. "Smart Buttons" save you time by making it easy to view all charts and graphs within a document and allow you to add your own notes or bookmarks to any section of a document. The IDC Research Reader will automatically sync your iPad bookcase with your online idc.com bookcase for a seamless experience.
