Paper
With so many companies and resources going paperless, eventually, the need for paper will be no more. Many schools encourage online learning, many companies encourage paperless billing, and even stores offer an email receipt option at checkout. Think of all the trees that could be saved!
Digital Cameras
For similar reasons that camcorders will be unnecessary in the future, digital cameras aren't very useful anymore either. Most smartphones have powerful lenses and don't require any of the annoying transferring of images. Remember the days of inserting your SD card into your desktop computer? Didn't think so.
