If there's one thing that's predictable in the technology world, it's that things change. Products that were commonplace ten years ago (PDAs, CRT televisions, fax machines) are quickly fading with the sands of time.
Today, there are many products we take for granted that will likely be dead in five years. Whether their features are being subsumed by other products or they are falling victim to changing business models, their days are numbered. Sure you may still find some quaint reminders in the back of SkyMall's Late Spring 2016 catalog, but for all intents and purposes they will be gone.
