If you own Wesley's Widgets, and want to promote your line of fantastic Sprockets in traditional media, it is likely that you will get more traffic by putting the URL sprockets.com in your ads instead of wesleyswidgets.com/sprockets/index.php. In addition, the shorter URL may be easier to give out when requesting inbound links from other sites, and people that like your sprockets may be more likely to link (correctly) to your site using the easy to remember short domain name than the longer URL. PageRank will still flow through the 301, even if it may get diluted somewhat, and again, don't underestimate the potential benefits this strategy may have in offline marketing.
As to the point that Canonical raised about the change in URL possibly confusing visitors, I don't think that will be a major issue as long as your ads appropriately brand your product. As long as the customer knows that Wesley's Widgets is the company telling them about Sprockets, they are not likely to be too put off if they notice that they are taken to a new domain.
Many many many companies have followed this strategy. In fact, Google's own examples of how redirects work in the search engine used xbox.com, which was an easy to remember domain name, which redirected to microsoft.com/en-US/products/index.aspx?prodid=somecode2347432 or something similar.
