Holy crap, it's the future!
Apple's next iPhone could be the T-1000's first ancestor. CrunchGear reports that Apple has bought out all the patents for a new material called LiquidMetal. While this stuff isn't quite the totally amorphous goo that the deadliest robot in cinema history was made from, it IS capable of being molded into a far wider variety of forms and retains kinetic energy incredibly well. A description;
"Liquidmetal alloys represent the first enabling materials technology since the creation of thermoplastics and possess characteristics that make them superior in many ways to other commercially-viable materials. First, they have an “amorphous” atomic structure, which is unprecedented for structural metals. Second, they include a multi-component chemical composition, which can be optimized for various properties and processes. Finally, they lend themselves to process technology similar to that possessed by plastics."
It's too early in the game for any speculations on this to be much more than wild conjecture, but the fact that Apple has gone through the effort to buy up these IPs means that they WILL be launching SOME sort of LiquidMetal product in the future. Odds are, the near future.
