They have denegrated everything that could have made it easier to take not at homes without pencil and paper. Typing it into an address book--you could lose them (like you couldn't lose a paper copy). You could make a typo on the house number (I have seen not at homes and calls with such sloppy writing that I couldn't tell if it was 54 or 64, and got sent to the wrong door). They say that batteries on those things die (as if pencils don't break or run out of lead, require sharpening, and eventually run out totally). And that was back in the 1990s.
Give them a few more years, and the Filthful and Disgraceful Slavebugger will come out with something against the e-readers. They are always behind the curve--remember how they ranted against disco in 1983, after it was past peak? In theory, I could load an iPad with a few books and web sites, including this one, and read that during the boasting sessions. Or, I could download pages off of Joy of Satan, including Exposing Christianity, and study how to perform rune magick or other forms of witchcraft while everyone else is studying a washtowel rag that speaks against that very subject. I could download pages from both here and Joy of Satan, among dozens of other sites, or even watch videos during the boasting session on an iPad.
