If you have a digital voice recorder throw it out.
What you are about to get is the next big thing for gadjets.
Imagine if you could talk into your cell phone and send yourself an E-Mail with serial numbers from that furnace you are looking at.
Imagine being able to send an E_Mail with a voice recoding even though there is no web connection.
Imagine dictating to your blog as you drive.
How much you ask!
