If I get a message, Google Voice allows me to listen to it on my phone or PC. I like that I can keep old voicemail messages for as long as I want and have access to them on my computer. My favorite feature is the voicemail transcription. The service will transcribe a voicemail and send it to me as an SMS or email. This is just frickin' brilliant. Being able to quickly read a message on my BlackBerry is so convenient.
