If I didn't live in a rainy hole (and make a writer's salary), I would so be ordering one of these up for my backyard. Cal Spas' Ultimate Outdoor Theater includes practically everything you need in a home-entertainment system: weatherproof 63-inch high-def LCD, killer sound system (two subs, four amps, and surround speaks), DVD/CD system, Sirius radio, and obligatory iPod docking station. (Gaming inputs are included, console is not.)
Plus, while you're watching "Old School" on that sweet 63-incher, you can also be BBQing up some burgers and mixing some margaritas. The Ultimate Outdoor Theater includes a five-burner barbecue island, cocktail station with blender and ice maker, and a martini bar with stools. Or you can just be lazy and relax on one of the three recliners while everyone else does the work.
In fact, if you live somewhere nice, what's the point in going inside ever? You've got a living room, a kitchen, and you've even got nature's bathroom all around you.
