FastCompany just posted an article about location - specifically, location-based services built for smartphones. There has been a lot going on in that world recently, notably Apple's patent for a location-based social network. Not that they'd be the first in that arena, but people have definitely been talking.
Not every company is so location-specific of course, but if location-based stuff like this seems like a good fit for your business, it might be a good idea to keep up with this series.
Take a look at the article here.
