You have to love the video activity from RIM these days... last week we saw a new youtube video showing the awesomeness of BlackBerry Messenger as a tool for dating (via the powerful BBM Flirt), and this week it's a BlackBerry Case Study looking at how BlackBerry Smartphones are improving one-to-one patient care at UPMC Mercy Hospital. It's an interesting video - definitely worth checking out. And with the upcoming release of the BlackBerry PlayBook I'm sure we'll see the benefits of BlackBerry extend even further into health care (they've already shown off a couple of medical apps for it).
