Well, as I said, I'm not opposed to the new way of doing things, or any new way for that matter, however, I don't want to abandon an old way until it's tapped out. Being in tech for 15+ years, I've grown tired of forced obsolescence, and just dropping an old way of doing things just because there's a shiny new way frustrates me to no end, as I'm sure it does for an incredible number of others. And if I hate getting left behind, imagine how they feel.
Plus, book signings have a special magic to them you either don't see, or have forgotten. The magic of having your 30 seconds in front of an author and having them sign your book is not only hugely exciting for some people, but it's also a great way to connect with fans and increase your chances (by as much as ten times!!) that they will in turn share that excitement with others, which will automatically increase your sales with little more effort on your part than a few simple pen strokes.
Now, if you had the chance to no less than triple you sales merely by doing a few book signings for those "poor out of date people who are behind the times and/or locked in the literary stone age", could you honestly say no? Dude, it's simple economics. Heck, if standing on your head for an hour a day clucking like a chicken could increase sales, I'd do it. Never dismiss a potential sales avenue just because it's "out of date". Sometimes those "out of date" people are loaded and have friends who are too!
