Unless I missed something, I'd say:
1. Original disk in drive.
2. Read mode.
3. Green button (makes ISO).
4. Put blank in drive.
5. Write mode.
6. Select ISO.
7. Green button.
Couldn't be steps 5 & 6 be automated ?
After I copied a CD, if I insert a blank one, it could automatically pass in write mode, with the last read image, no ?
This would be a time saver, obviously, but also be usable by beginner users (think about my mother ;-)
