I just read this post on GigaOm about a yet-to-be-released app for the iPad called Mindmeld. It’s a conferencing (Skype like?) app that listens to your conversation and provides relevant information about the things you’re talking about. While you are talking! Without you having to do anything?!
I won’t pretend I understand how it works but it looks impressive. It’s supposed to come out next month. I wonder how much it will cost? I may have to try it out.
