I have sort of rediscovered Google Voice. I have been using it since it's introduction. It converts voice mail to text and sends it as an SMS message and email. Makes it very easy to check voice mail. It allows calls to be made from the computer. New is porting where a mobile number can be used through the GV system instead of needing a wireless carrier.
Cool stuff. Check it out when you get the chance. Some things are a bit hinky. Being able to select all in the Inbox like in GMail is not a feature.
