The most annoying part of setting up a home theatre is, well, setting it up. Plugging components together, getting them to play nicely, and all that jazz is just a big roadblock between you and the vegetative state you plan to put yourself into as soon as that HDTV is fully functional.
That's why combo devices like this are where it's at. The DY-PJ001H All-in-One DVD projector makes setting up that projector-based home theatre pretty damned simple. Just set it up, pop in a DVD, and watch as it hits the wall right away. Sure, you'll need to hook it to speakers, but otherwise it's a pretty straightforward setup. And hey, if there's one thing I know, it's that laziness and home theatre goes hand-in-hand.
