BERLIN -- Washing machines that decide how much detergent to use and coffee makers that learn just what kind of brew is to your liking are some of the cutting-edge appliances being showcased at this year's IFA trade show here, in what promises to be a heated competition bewteen Asian and European rival electronic companies over the latest clever devices.
The event, opened for media previews on Wednesday, is one of the world's largest consumer electronics shows, along with the annual CES expo held in Las Vegas. Last year, it drew 180 exhibitors and more than 250,000 spectators, helping vendors secure 4.7 billion euros ($5.5 billion) in orders.
