When people talk about technology we can think of a ''world'' that has something new in every minute. It's hard to say what will be the ''the big point'' (leading technology) in the future. Spacialists are currently trying to improve things wich have just been discovered. Changing the channels of a TV by just waving the hands, for instance. But there are other equipments more useful for the daily life. An interesting thing is a special machine where is possible to download books. Imagine studing all the subjects with just 'one book'. It would be amazing, wouldn't it?
