The long wait for a 64-bit version of Android on smartphones is coming to a close, with Intel on Monday showing a version of the OS running on a handset. The OS was shown running on a smartphone with Intel's new dual-core smartphone chip code-named Merrifield during a press conference at Mobile World Congress in Barcelona. Intel had already shown tablets running an unfinished version of 64-bit Android with its Atom chip code-named Bay Trail.
