That was too short an interview to really discuss the topic, so I don't think any of them came out of that in the way they had hoped.
I think he was a bit jumped on to.
I didn't really like the way he made his point, but I think sadly he has got one. Whether we like it or not, e-books are becoming the norm. I'm with the "or nots" on this one, I was really disappointed to find a new Stephen King book on sale only as an e-book and I hate reading downloads.
But the presenter was quite quick to jump on him when he said "Swedish" instead of Norwegian and I think it put him on the defensive.
And his "talk about me" comment seemed to be to try and use his own reading habits/preferences as an example for the discussion. Which was flawed since he had previously complained that 15 year olds are too old to be a valid age group for study.
But I think they were all on about the same for jumping on, dismissing and bullying each other, probably because they had a very short time slot to discuss things in and they all wanted to get their own point across. I don't think he behaved in any worse a way than the woman who was being interviewed with him (and she called the research Swedish too) but I didn't really take to him based on what I heard.
I haven't paid the books or the author much attention so far, as LO is still too young for them yet. From this thread he seems to be a qualified historian in the same way that Gillian McKeith is a doctor, is that right? 
But I will say that at age 2 1/2, LO loves both paper books and the e-books he has on the i-pad, although I'd say he seems to prefer the paper books more at the moment. The i-pad is fun sometimes, but it's the 'real' books he likes to look at himself.
They needed far more time on this subject.
