Yes, I agree. Prints are great but not if you have to pay extra to get them. With a CD you can have as many images as you want or at least the ones you really like and get as many prints as you want afterwards any time you need them. Most photographers have no problem with giving a CD with images after a shoot. Often it takes a long time for them to retouch all the images or get around to giving prints so simply burning a bunch of images to CD is much more cost effective and timely.
For models, it doesn't hurt to learn Photoshop and simple things like cropping, lighting and fixing blemishes, etc. Plus, it's fun once you learn how to do it!
