I've used Google Talk 's Voicemail feature for the first time with my uncle. There are two aamzing sides to this first timer.
First is the software itself, Voice mail is a great idea. I hate typing long e-mails to friends, and thats why I get a lot of "why aren#t you writing to me"'s. What I am gonna do is give'em a Google Talk Account (if I haven't still done so), and send them voicemails from time to time. Teh messages come to your mailbox as E-mails, and you can either listen to them on built -in player or download as mp3 file.
Second interesting point is that it got my uncle interested to it. I mean he is not a computer illiterate, but he is not a geek or power-user either. Yet, Google's simplicity lets even not so advanced users play around...
And best of all, google talk is still beta :)
