Summary. E-Readers, or electronic reading devices, are becoming a household item; however, there exists little research on the usability of these devices. This study investigates the ease-of-use of three e-Readers (iPad, Kindle 2, and Nook 1st Edition) for basic e-Book navigation. Participants (N = 17) were asked to complete a series of book tasks (e.g., opening a book, bookmarking a page, etc.) on the three e-Readers. For each device, participants were asked to rate the task difficulty and the facilitator recorded completion time and number of taps to complete the task. Participants also rated each device in terms of perceived workload and satisfaction. After using all three e-Readers, participants were asked to rank each device on a series of attributes (e.g., screen size, bookmarking, glare, etc.) and overall preference. Results revealed that the iPad was better than the Nook and Kindle on all performance measures, task difficulty, perceived workload, satisfaction, and preference. The only task in which the iPad proved to be more difficult than the Nook and Kindle was the note-making task. Suggestions for improving future e-Readers are discussed.
