We're still reeling from Samsung's teaser video showing (what's almost certainly, definitely, probably) the Nexus Prime in a quick flash. Now filmmaker and Android enthusiast Joe Lancaster has put forth an interesting hypothesis: the Nexus Prime will dock with a companion Samsung tablet, a la the upcoming Asus Padfone. Lancaster has a modified image from the teaser video to back up his claims.
The crux of the hypothesis centers around the three gold/copper circles seen on the side of the mystery phone. These may be electrical contacts, and Lancster believes that their purpose is to slide into a dock for a larger tablet, much like the Motorola Atrix and DROID BIONIC laptop docks, and alluded to in the "combination" theme of the Samsung Unbox Event video. He further hypothesizes that the black arc sen behind the phone is actually the profile of the tablet, which features a similar concave screen. Android Ice Cream Sandwich is designed to bridge the gap between Gingerbread smartphones and Honeycomb tablets.
Personally, I just don't see it. The circles probably are electrical contacts, but I'm guessing they're for a standard desktop/car dock, in a similar fashion to HTC devices like the Rhyme. The practical aspects are puzzling too: while the Nexus S curve is interesting and even fetching on a smartphone-sized device, a tablet with such an extreme curve wouldn't rest well on a flat surface, and the overall thickness of the tablet (even if most of it was empty space) would make it precarious in a bag or slip case. I think we're looking at a little stylish graphic design and a lot of imagination.
Get your speculation in now, folks - we'll know the truth next Tuesday, October 11th, when Samsung's Unbox Event steals the show at CTIA.
