Technology conferences are a way for the tech industry to showcase their newly developed technology.  In the IT industry the first one out of the gate often wins the race for the consumer dollar.  Trade shows like the CES are a very big deal in the industry and if you work in IT you should try and take on in at least once.

Technology trade shows do far more than just give you the chance to see new developments it allows you to make connections.  If you are one of the smaller companies that work in the technology sector then you can network with some of the big players and hopefully create a lead or two for new business.
