It doesn’t bother me too much that DVDs and streaming video have taken away the need to catch a favorite holiday movie on the night it airs on TV. Nor do I mind that I can listen to a favorite carol any time I like thanks to the magic of iTunes and mp3 players. But the one thing I definitely would miss if it were to be displaced entirely by modern technology would be the holiday ritual of sifting through a nice big stack of catalogs.
