The next big thing, will be the resizable tablet....imagine a device that could be the size of an iPad Mini, but could easily expand to the size of a regular iPad or even larger, if you want to watch videos on it.
File for a patent on it! Just kidding, others probably have. What with all the work on flexible screen technology, this will be in stores in a few years. Remember "Red Planet" with Val Kilmer? They used tablet screens that rolled out of tubes held in their hands. When done, the flexible screen rolls back into the tube. You can make the screen as wide as you wish.
