Including a CD-ROM with AutoCAD and treating it as an integral part of the value added of the product, not a glorified ``bonus disc,'' creates a large technologically-supported incentive for owning a legitimate copy. CD-ROMs are easy to copy but very expensive (for the next few years) to duplicate. Huh? What I mean is that if you're willing to buy 600 megabytes of hard disc and fill it with the contents of a CD-ROM, there's no problem doing so, but most users will opt for using the CD-ROM that comes with a legitimate copy instead. What would be on the CD-ROM? Use your imagination ...a full hypertext indexed reference manual ...annotated source code for model ADS applications ...a library of a million useful symbols ...ten thousand fonts.... Let your mind free run and see what you come up with.
