Motorola once had a "laptop" that you attached one of their phones to--but, like some of the others, it only worked with that phone.
This thing is advertising almost any phone model that runs android, which is what makes it different.
Me, I'm more of a laptop guy than tablet. I currently use my Galaxy Note 4 on the road with an HDMI connector to the TV, and bluetooth mouse and keyboard.
Galaxy Note 7 is due to come out around September/October; I've sent a message to these guys asking if they can confirm that the Note 7 will work with it. If not, well, it's a deal-breaker for me.
