But thanks to advancements in image compression, microprocessors and wireless-data bandwidth, the smartphone may prove to be, like beepers, an essential tool for on-the-go doctors.
Such compression is important given that YouTube users upload some 20 hours of footage per minute; by shrinking the files, YouTube needs to buy less bandwidth from Internet access providers.
