Promotional Gifts - Which Are the Best for Trade Shows and Exhibitions?

I was on the new Q&A social networking site Quora the other day and found a question very similar to the title of this article. I didn't like some of the of the answers. Many people were insisting that gimmicky gifts were the best. A few even said that exhibitors should leave their promotional pens and mugs at home as they are old hat and boring. http://ping.fm/xMSZM
