I just noticed something. I was sitting in my relaxy-chair (not a TM) and reading on my iPad, which was on a big floor stand right in front of me. Maybe because of a good lunch, I started feeling good in an interesting way and I closed my eyes, wanting to meditate on it a little. And I noticed that even with my eyes closed, I could *feel* the tablet right in front of me, and I pushed it away.
And I think this may be a main reason why many people prefer paper-books or non-lit ereaders over tablets or phones: because a lit screen is “pushy”, it walks into your space whether you want it or not.
It’s probably a big part of why I love tablets (and big phones) so much. They do a lot of the attention work for you, they walk towards you as it were. But, it’s the same as with quite outgoing persons; it’s often a good and pleasant thing, but in certain moods you may not welcome people or devices who walk into your space.
