I would like to buy an e-reader, there is only one thing that is bothering me. A 7-inch e-reader is slightly bigger than a standard smartphone. That means, it only fits 1/4th of the text of a standard printed book.
Doesn’t that break the flow of reading to constantly changing pages? I don’t want to decrease the font size as that would be straining for the eyes or buy a 10inch reader as that would be way out of my budget.
Is it an acquired comfort with the small portion of the text available at one point or am I the only one bothered by it so it’s a non-issue for everyone else?
