Who hasn't read a text message, directions, a menu, or news story, an article or even a book on a phone? Books are possible though difficult which is why we have dedicated readers, and tablets of various sizes.
Here is an article about the Smart Phones Screen sizes, from 3.5" to 5." Remember that eReaders used to come in 5" sizes, then passed through the 6" size to the new 7" size which is also the size of a lot of regular tablets.
Some have even claimed that you need 9.7" to give the perfect "experience" and "magic."
