Certainly, they're for the self-starter, but I think they're oriented primarily for the business user. A small business could buy a set of the WordPerfect videos to lend to their employees so they could improve their skills. If you intend to lend these to more than one employee, you should probably check with KeyStone on how to do it legally. Whenever I'm asked which word processor should a company use, Word or WordPerfect, I usually ask what the company is doing before replying. In cases where it doesn't make any difference, I advise having both available.
Hard disks are now cheap so there's plenty of room.
If a firm has both available, they can hire whom they want. KeyStone makes videos that cover Word as well as WordPerfect, so I'd have both of those around as well. In fact, they make videos for a lot of programs. Check their web site. If your budget is limited, and you need some basic stuff, I'd advise buying the first set of three.
