Well, HP and Dell were just an example. This could be used by anyone who wanted to plop an IR camera in something. A refrigerater, a tv, pretty much anything. By creating software that can run on a generic processor that needs a relatively small amount of memory, they might be leaving the path open for allowing manufacturers an easy way to create hands free control devices by using MS's already developed system. And this is only if MS's software is better than other IR systems that are already about to be released to the market.
