Anyone who takes digital photography seriously should be working on a calibrated monitor, plain and simple. But, because it's a bit expensive and it's not actually a part of the physical photo capturing process, it's something that often gets overlooked. X-Rite's ColorMunki Smile makes the entire calibration process extremely simple, so even if your photographically-inclined friend doesn't know much more about the process than you do, he or she won't really be able to screw it up. In the end, it'll ensure that their pictures look just as they want them to and will even likely save them a fair bit of money they'd otherwise spend on bad prints.
