Dazzling displays and high tech gadgetry. Tech giants show off their latest inventions. A liquid sucking vacuum cleaner from Philips is just one of the offerings at this year's IFA electronics fair in Berlin. Or how about a phone that will survive a dip in your bath? This Sony smartphone can take a dive for up to half an hour in up to 2 metres of water. According to the deputy editor of C'T magazine, IFA is successful because of its focus on the end user.
