Bruce Weinstein, who writes "The Ethics Guy" column at BusinessWeek, has an interesting take on our obsession with electronic gadgets. In critiquing the iPhone, he says the "i" should stand for "isolation."

Throughout the day, the more we bury our heads in devices that let us chat, listen to music, read e-mail and shop, the more opportunities we miss for direct social interaction, he writes. Of course, he doesn't mention all the interaction the Internet also facilitates, connecting people across the globe who ordinarily would have no way to meet.

Still, I found his column thought-provoking. But when I replied to an e-mail from him last night, I had to confess I read his column on my BlackBerry. He then admitted to being online from his laptop at 10 p.m. Face it, we're all hooked.
