Want to walkie-talkie like when you were a kid? Motorola cell phones offer a push-to-talk option on many models when you purchase a cell phone through a wireless carrier such as Cingular.
Push-To-Talk may give you the freedom you felt as a kid, but has grown-up applications. It's extremely popular for commercial businesses because it allows co-workers to access each other in real time without the hassle of dialing.
Note for kids on a budget: Some phones only let you activate will the push-to-talk feature if you opt not to make outside calls on the regular cell phone function. This is a convenience for companies looking to save money. The best solutions sometimes come from childhood ideas.
