I wont buy Blue Ray at all yet... It needs a few years to see if it can overcome the Sony Proprietary mess.
Anyone remember Sony's "High Quality" VTR's, the Betamax?
Yeah, didnt think so.
If you do, and would like a library of Beta tapes, let me know. Fool me once, shame on you, Fool me twice...
Betamax... awesome! But the standards war has already been fought. HD-DVD lost and Blu Ray won. Microsoft is the new Sony in proprietary losers.

But I'm with you. My entire point is that I think by the time you buy in, the entire DVD market will have become functionally obsolete.
Regarding bulb life, very good point, although the same is true for rear projection LCD or DLP tvs. It's a built in expense.
That said, the bulbs aren't typically expensive enough to buy a new TV, although they'll easily run you a couple hundred bucks. Also, the way you say it, 2000 hours doesn't sound like much time... 83 days if you run your TV 24 hours per day. For a more realistic comparison, consider that a full time job is 2080 hours
per year at 8 hours per day, and most people watch TV a couple hours per day, the average user can expect their bulb to last 3 to 5 years.
For placement, a room that is dark or can be made dark is the best, but what that really means is a
screen area that is dark. The room can be brighter, but where the screen is... THAT should be dark. What I'm driving at is some houses have recessed areas that can be shielded from a lot of ambient light, which is perfect for front projection.
You'll also want to get a projector with good contrast ratio (although I'd beware of claims up over 8000:1) and a high lumens rating.
