I see tihngs like that becoming common place. I think (and am suprised we haven't already seen many) HDMI docks for phones that do what that video does. I know one exists for Note 4. It's like $40 bucks. I may get one.
But essentially, dock your phone to a device that has USB support for keyboard & mouse, and an HDMI connection, and BAM! instant computer.
I've done it a few times with my tablet and a bluetooth keyboard. It's kinda neat, but not quite as useful without a trackball.
A.J. I'm not trying to be mean but why are you constantly plugging your website here instead of just posting your review on ML. It kind of defeats the purpose of the review section. I fully understand that your site is new but can you find a different way of plugging your site? To me its unprofessional to go on a site and say hey go to mine, i have all of these reviews and so on.
Plugging his writing is fine. There is even a self promotion category just for that. A review in the water closet isn't the best taxonomy but I feel that that is all.
