Google gives away a lot of good stuff for free. That struck me last year when I downloaded the free Google Maps app to my smartphone. It turned the phone into a handy navigation system and killed my desire to buy a $100 standalone GPS unit. So I was intrigued to try Google Voice. That is a service that gives you one phone number that connects to all of your phones. It also manages your voice and text messages and gives you a way to make cheap or free international calls. It comes as a downloadable application for cellphones and as a Web-based program.
