by the way, this projector works great in my family room and although i haven't bought a screen yet, my wife and i are content to watch hd content and stretched non-hd content on our wall. looks fantastic and compared to plasmas i've seen at retailers, this projector provides just as good of a picture with the ability to project a large screen for movie night. you don't need to turn off all the lights with this projector, but during the daytime it is best to have the curtains half shut.

Why XP on a Mac? Well, it has to be the right situation, but for me it was work. I have to have xp for my estimating system (I manage a body shop). When the boss man gave me money to buy a computer, I gambled that Parallels would work and the networking would be fine...
If I had placed bets I would be rich because this handles XP like a champ even though I still only bought my macbook pro w/512 mb ram. I am able to network and share files in xp and use the estimating system for all the estimates I need to write. When I get home I keep parallels closed and use the OS that I love to use.
So anyone who wants to argue "why XP"? It's because we don't like pcs but have to live with them and can run xp in a mac as if it were a wee little program.
