Modular Phones
This was a nice attempt at one-upping the iPhone industry, but no one really seemed to care. Phone companies tried developing a modular phone so that the user can customize it to their liking. Turns out, that's not what the consumer wants whatsoever and the phones flopped.
Google Nexus Q
Ask any tech writer from 2012 about this thing and they won't even know where to start. The Nexus Q was a device that streamed from YouTube, Play Music, and Play Video. It famously had weird connection issues and barelt worked, and even required an app to change any of the settings. Google eventually pulled the product off the shelves to relaunch it after hearing consumer complaints, but that never happened.
