I do find that my vision pattern is not the same when I read an article on my iphone. I find that my reading is very "skippy". I don't track well. Why? My theory is that I am looking for "just the facts, Ma'am". I want instant gratification from online articles.
I haven't paid much attention to how I read an ebook on my Kindle or nook ereaders though. Lately, the books that I've been reading are from a favorite series or they are titles that I anticipate wanting to keep or wanting to lend and so I've been buying and reading actual printed books and not ebooks, for the most part.
I've also found that my brain power has ebbed a bit the past couple of years. I do not think it is a coincidence that I have read less the last couple years. We will choose not to pay heed to the fact that time rolls on and I have a birthday tomorrow. I'm sure age has nothing to do with it.
What say you?
