5. Intel (INTC) Wireless Display Sometimes it's not the idea that's bad, but the way it's implemented. Intel's idea to wirelessly transmit 720p high-definition signals from a laptop to a television screen was not only good when it was introduced at CES in 2010, but should sound awfully familiar to anyone who owns an Apple ( AAPL) TV box today. Unfortunately, it made it into only a select few laptops and required a $99 set-top box to use. It also never found its way into smart TVs, Roku and Boxee boxes, Blu-ray players or any of the myriad other devices that ended up giving the laptop a pass and bringing online content directly onto living room televisions. Like Apple TV, it's still a pretty efficient way of putting the contents of your laptop's screen onto a television. Unfortunately, as more consumers shift to mobile devices, there's less demand for what's on fading laptops.
