Dean Guitars has an innovative new USB Upgrade for many of their acoustic guitars which I think is an excellent idea and is a very useful feature for songwriters on the go:

This “guitar industry first” technology allows you to easily plug your Dean acoustic directly into your iPad or other mobile device. For the first time ever, you can capture that moment of inspiration in GarageBand or your favorite recording software without needing additional hardware. Learn more at DeanGuitars.com and Get your Wings on the fly with the Dean USB upgrade!

I really like the headstock in the video above Dean have done a great job with their acoustics.
