With this phone, you could just swap in different modules like camera, speaker, extra RAM or battery as per your need. Now the time has arrived when you could customize your phone piece by piece.
Going out for a trip, just pop in a bigger battery. Or swap in extra speaker, if you're planning to throw a party tonight.
As Arthur C Clarke once said, Any sufficiently advanced technology is equivalent to magic." This Modular Phone with lego like different modules proves that it is no less than magic.
