Reading on an iPad is better than a Kindle, a study by Nielsen Norman has found. Both were slower than with real paper, but the iPad was considerably quicker for reading at 6.2 percent slower where Amazon's ostensibly better Kindle was actually slower, at 10.2 percent off of the time for paper. Apple's tablet also edged out the Kindle in usability, as iBooks not only had more clearly defined fonts but a much easier to understand page marker.
