I discovered this loathsome new invention in some anti-Canadian snarking on Gawker. Atwood et al are pretty nervy promoting this higher-tech autopen as anything more than an excuse to multitask watching Canadian Idol and promoting your book at the same time.
I'm not an autograph collector, so I'm not sure I understand the appeal, but isn't part of getting a book signed the commemoration of meeting an author you like? That whole Patricia Polacco "hand that touched the hand that touched the hand" connection? I don't care how Long your LongPen(tm) is, Ms. Atwood, I'm not letting it near me.
