This is very creative, but be aware this isn't a Google product. A couple observations:<p>1) Making the TOS presented so prominently is a bit surprising and imposing. Their placement makes me wonder whether this is a cute, harmless gift or something worse. I know Google's "Don't Be Evil," but this site is run by someone else...<p>2) This isn't Google. This is some company that Google's marketing department contracted. If you look at the source page, you see this is running on stock AWS and might even have been an "off-the-shelf" solution Google added their name to.<p>While I have faith Google set up a reasonable contract to protect my info, I don't know or trust the third party to handle my information properly.<p>3) Maybe it's the geek in me, but I'd be 100x more excited if some employees put this together during their 20% time. Seeing that it's clearly a marketing bit end-to-end means I almost don't want to share it with friends.<p>4) It would have been nice to download the MP3 and send it over email myself. A phone call is a nice way to advertise Google Voice, but it sure is hard to share with friends and family after the event.<p>5) Related to the MP3, it doesn't include any of the advertising or promotional messaging I would expect during the preview. I would like to know the entire experience I'm sending to my loved one, not just the personalized message. If it requires my loved one to submit an email address or listen to 30 second advertising, I may not want my loved one to hear it. This may be undue paranoia, but I feel like I've had to keep my guard up with marketing companies.<p>Net: A cool, creative idea but overall underwhelmed by the execution and unlikely to use in practice.
