More than 127 million mobile phones will be enabled with commercial Linux OS by 2012, up from 8.1 million in 2007, according to the "Mobile Linux" report from ABI Research. Shipments of devices using Linux as a real-time operating system (RTOS) replacement will pass 76 million units in 2012, up from nearly zero in 2007.
"Linux in the cellular phone is not a question of 'if,' but 'when,'" said Stuart Carlaw of ABI.
The main challenge Linux has faced in single-processor devices has been latency, but it is Mr. Carlaw's opinion that fixes are appearing.

"Innovative solutions such as PREEMPT_RT, the VirtualLogix virtual operating environment, and the use of RTOS executives over Linux kernels look set to deal with latency issues," said Mr. Carlaw. "However, the industry still needs to understand the total cost of ownership for Linux solutions, and it must create a common set of APIs [application programming interfaces] to enable economies of scale for third-party developers."
