From your article: “First of all: doctors say that reading on a screen won’t cause any harm.”

I feel like the post originating this discussion was somewhat alarmist. It's definitely true that some conditions that ereaders (of varying types) present can cause fatigue faster than reading a printed page in a well-lit room.

And please don't take my statements as proof, because I'm not offering anything besides the null hypothesis: reading is reading and there isn't any special magic to screen reading that makes it an eyeblaster.

I'm certainly not going for the "staring at a light bulb" argument... I think in the end it's probably a rather minor difference, akin to bad paragraph typesetting, bad fonts or even ligatures and hyphenation. Certainly not roasted eyeball territory...

In the end, what people like will be more important. I remember reading some studies where font choice on readability was tested, and the font that tested best wasn't the preferred one. Probably the same for reading devices. Let's say you compare the Kindle and the iPad for high school use. And let's say independent tests made clear that reading comprehension for the Kindle is better. Then you still would have to consider whether the kids aren't much more likely to pick up the iPad in the first place. Reading slightly slower is better than not reading at all. (Well, never mind that choosing more interesting books would probably make a bigger impact. Friggin' Lord of the Flies...)
