If Home.Price > Business.Price then it would seem that they are hoping businesses will see the lower price and do all of their computers & accessories through that manufacturer. Or, of course, they know that home buyers aren't as tech savvy and aren't going to notice.

Whenever I think about market segmentation and prices I think of Joel's great article on it: http://www.joelonsoftware.com/articles/CamelsandRubberDuckie... (2004)
