Actually, not quite. I see this device being better for the corporate space than the consumer space. This is exactly for the people who DONT want to carry a laptop around. Have you ever had a job with a "work from home" option with a company provided laptop that you had to lug back and forth to work every single day? Now imagine if you just had a cheap device at work and a cheap device at home, and only had to port your phone back and forth, and could easily dock into both.
This thing is essentially an alternative to docking stations for laptops, only now it is a docking station for your phone.
