I've heard that DLPs have a shorter life span than LCDs. Is this correct?
Not really. what dies is the bulb. With LCD your backlight might go to. Unless you got one of the fancy LED backlit models, which should have a much longer service life than the flourecent backlit ones.
Some DLP models (Toshiba) had a bad track record on lamp life. Other ones are fine. Sony made some great projection tvs based on LCOS (sony calls it SRXD) and it is a beautiful technology.
The bulbs (which, IIRC, are usually HID, not flourescent) burn out every few years. On the other hand, the actual projectors can last a long, long time.
The big advantages of DLP projection are light weight, a matte screen that reduces glare, zero risk of burn-in, and the gargantuan screen you get for your money. Disadvantages are high screen reflectivity (bright light is a bigger problem for DLPs than for LCDs), large size, bulb replacement, and poor reliability in some models.
A friend of mine has a Mitsubishi projection TV. He bought it pretty recently, but so far it's been excellent - great picture quality, great brightness, great contrast, and none of the DLP problems people have told me about. Background light in the room is not a problem, if only because the TV is so big that it completely blocks out all windows in the room. (I'm not kidding - it's freakin' huge!)
