Query: Simple and easy to use!

I bought the recorder used and it works great! I have a mac and uploading the finals is very simple. You hook the device up to your computer via usb and drag the tracks in to iTunes and label as you would like. I use a different folders on the device to keep recording of different classes straight. Overall I could not be happier and I wish I had started using a recorder earlier in my academic career.
