From Cnn.com:
(Mashable) -- It takes longer to read books on a Kindle 2 or an iPad versus a printed book, Jakob Nielsen of product development consultancy Nielsen Norman Group discovered in a recent usability survey.
The study found that reading speeds declined by 6.2 percent on the iPad and 10.7 percent on the Kindle compared to print. However, Nielsen conceded that the differences in reading speed between the two devices were not "statistically significant because of the data's fairly high variability" -- in other words, the study did not prove that the iPad allowed for faster reading than the Kindle.
A total of 24 participants (10 is about average for a usability survey) were given short stories by Ernest Hemingway to read in print and on iPads, Kindles and desktop PCs. Hemingway was chosen because his work utilizes simple language and is "pleasant and engaging to read."
The narratives took an average of 17 minutes and 20 seconds from start to finish -- enough time to get readers fully "immersed" in the stories, Nielsen explained.
