Text messaging is already one of the fastest growing sources of revenue for service providers.
Any product which facilitates text entry and thus leads to more messages being sent is of supreme value to service providers. As the network of advanced, accelerated services grows, consumers will be increasingly drawn to abandon their legacy phones in favor of LOPT-capable phones, fueling OEM sales. Thanks to its extremely small footprint in memory, OEMs can easily provide the benefits of LOPT in all their phones, adding value even to basic phone functionality, such as the address book. Both LetterWise and WordWise can be provided in a single phone, allowing OEMs to serve the text-entry needs of a broad spectrum of consumers.
