I've had my new iTalk unpacked for about five minutes and I'm amazed by how simple it was to use (just click into place, and push to record). Playback is easy and you can even use it as a small, tinny speaker.
It's crazy to think you can store something like 20 hours of your own recordings with this and my mind races when thinking of how I would have used this technology when I was in college (napster could have been loaded with lectures, not music). I'm also thinking it could serve as a pretty cool way to record Kay and I talking about the upcoming baby for later (much later) playback.
Imagine how freaky it would be to hear a recording of your parents from 20 years ago, debating what to name you, talking how much you kick everyday, and how much they're looking forward to meeting you.
update: this is exactly what I'm talking about. A great use of available technology.
