Those of you who have yet to join the Google Voice bandwagon no longer have an excuse. Google has opened up the service to all US residents without an invite which is sweet! If you want to know what Google Voice is all about check out the video below:
The service gives you one number to ring all your phones, voicemail that works like email, free calls and text messages to the U.S. and Canada, low-priced international calls and more all from one portal. My favorite is the ability to respond and receive SMS through email. Its pretty sweet and its still free which is amazing. Hopefully Google keeps on developing the solution and adds the ability to port your number in the future since that is a key missing feature.
