I can't help but think 'turn them off' is the most obvious answer here. The author seems to think he needs the iPad/laptop to fall asleep. Well, that's simply being untruthful to yourself. It's just a habit, and with some correct training (and eventually even seeing a psychologist) he can replace it with another, probably healthier, habit. Like reading a book or meditation.
So, you turn on the TV in the bedroom and annoy your sleeping partner - no, this won't do. So you go to another room to watch and fall asleep elsewhere and relationship issues ensue with your sleeping partner. Nope, not gonna cut it.
Tablet, dimmed, in bed, with re-runs ... and it works for this guy.
I know he mentions books in the articles but put them away because they either were either too exciting or too boring. To me that sounds like not having tried hard enough. As I said: replacing such nightly habit with another one isn't easy.
I've found success with a formula much more like yours (no blue light for an hour before bed unless absolutely necessary). I understand what he means about books being too exciting or boring too. What I've done is what he does with TV: I reread books (I also lean towards very simple to read books). Just this year I've done Liar's Poker, Moneyball, The Hobbit, and am working my way through the original Bourne series.
He tried reading and stayed up reading and it didn't work. But what about stopping all electronic things after 21:00 and then reading on your couch NOT bed, then go to bed at 22:30? You'll sleep like a baby.
