One thing I don't think I saw covered is LCD/Colour displays help draw people in on location. They are also good when people are watching someone play, it helps attract people and gives them more to watch.
From an operating standpoint I am all for them. I was unsure about a hobbit but am getting one now specifically because I know it will attract people. I put a WOZ out with some other games and play on my older games stayed steady (they have not taken a hit despite adding in WOZ) while WOZ is doing very well. More people are playing now since I put WOZ in. Same location we have had games in for a couple years but it acts like a flame to moths.
So for locations I am a big fan of LCD displays. At home it is not a big deal to me though.
