Projector as monitor?

What is the downside to using a projector as a full time monitor
replacement? I haven't checked, but I imagine that an SXGA projector
is kinda pricey, but maybe not much more than a good quality flat panel
monitor? If I can stand the price and space it takes up, what else?

I like the idea of not focussing 18" away all the time, especially
since I do it almost 8 hours a day anyway while at work. Plus, it
would double as a big screen DVD player.

The bulbs are expensive, something like $500, with an extremely short
lifespan.

Assuming you mean a front projector throwing an image
on a large screen some feet away:
- resolution
- bulb life/cost
- filter life (if LCD or LCLV)
- phosphor life (if CRT)
- fan noise
- waste heat

And depending on your usage,
- eyestrain,
from frequent shifts of focal distance from desktop
items (papers, keyboard, etc.) to the distant screen.

Can you get a 1920x1200 project for $900?
That's what desktop 23-in. LCDs are selling for.

You also may have a logistic problem, if the video cable
needs to be run more than 3m or so.

A rear projector setup has additional problems,
principally the hot spot and color shifts off-axis,
making it useless for any critical color or grayscale
work.
