Of course, such a thing only happens when there's overlap. There's not much use for an XBox or a Wii in a company, with the exception of having a fun and games room as an added benefit to employees.
But when a product is useful for the enterprise and popular amongst consumers, it will enter that space, simply because enthusiastic employees can move mountains. See for instance Linux's growth in the ninties, in spite of Windows, IBM AIX, Solaris, HP-UX, or other OSes that were definitely more ready for the enterprise. Basically an immature Unix clone, that can't even keep binary compatibility between versions, is killing all proprietary Unix distributions, except OS X.
