So she has just discovered that the HP Envy does not include a optical drive.
Admittedly I had overlooked this feature (or lack of) of the optical drive. Although in most situations these days I hardly use a CD or DVD but she might be different. when pointing this out to her, she was a little set back as the main point of her getting a Windows PC was gaming, and her games are on DVD.
Although this can be easily solved with an external optical drive, this maybe a big set back and may force her back to the drawing board for her next laptop.
