HTC is considering the possibility of making its own mobile OS, the company's CFO Cheng Hui-ming mentioned in an interview on Tuesday. He was careful to note that HTC still "continue[s] to assess" its options but said that there could be definite advantages to making both hardware and software, like Apple and RIM do for the iPhone and BlackBerry. It would depend on "multiple factors" being in alignment to justify the move, Cheng told Bloomberg.
