Via Jason Landgridge - You can get your mobile voicemail sent right to your PC either in email or on a Vista Gadget right on your desktop. And it's Free! I was impressed.
This would have been extremely useful last week when I was out of the country and my phone was out of comission. I was scared to turn my phone back on after it being off for 4 straight days and sure enough - I had a virtual ton of voice mail.
Side Note: It's funny - I don't think anyone actually listens to the voice mail prompt. Even with an "out of the country - try my email" message, people leave me a lot of voice mail. I even got one that was a telemarketer offering services for SRT Solutions when the prompt also stated that I work for Microsoft.
