The Handheld Hospital – mobile apps and peripherals making hospital functions cheap and portable

Mobile applications, peripherals and add-ons are becoming sophisticated enough to perform tasks comparable to their hospital equivalents, at price points that are more accessible to members of emerging economies. Although they often offer only basic functionality, these devices approximate vital diagnosis protocols closely enough to provide people in remote areas with immediate diagnosis.

Lots of great examples!
