Pro #1: They are much more comfortable than upright bikes are. People who have only had uprights and insist that "they're perfectly comfortable" don't know what they're talking about. You could probably comfortably ride a recumbent at least 2 or 3 times farther than you could on an upright bike, and padded shorts and gloves aren't required--many high-mileage recumbent riders don't even own any padded shorts at all. There's no hand pressure or neck strain, and little or no seat pain at all (most recumbent models are only available with one seat, unlike upright bikes, where the shop has a wall-of-seats for you to choose from in the hopes that you'll buy a bike).
Pro #2: They can be faster than an upright bike, for the same pedaling effort. Most of the faster recumbents are not the cheaper ones however (but not the most expensive ones either).
--------
Con #1: they generally do weigh more, and don't have the "lively" feel an upright bike does.
Con #2: they can be more hassle to transport; many recumbents won't fit on standard car-mount bike carriers.
Con #3: (semi-related to #2) if you use your bike with public transportation, then be aware that recumbents may not fit on public-transportation bike racks either (this is a limiting factor for many people who bike/train or bike/bus to work).
