internet and my guest

I had a couple as guest to my house for the last weekend. we sure had good time while we were out, but we could not have much fun while we were inside. My husband and I noticed that our guests like to play /work with their individual laptop rather than have some friendly fun time with their host. I do not think we were the problem, because they did not much conversation with each other either.

How far we want to let this dumb technology take over our life? I am a computer person and fascinated with this brain power tool, but know enough that it is just another tool and not my companion or it is?
