@cliffwade No, I took the optical drive out of my laptop and replaced it with a second HDD. That said I do have (and already had) a portable usb dvd drive just in case... I used to have a client who would contractualise financial models by burning two copies to CD, then both parties would sign both CDs with a marker pen, and each party would get one each. That went on for a long time after it became hard to find CD drives.
