Why are you adamant about it being in the living room?
kitchen island unit: .... .....while it's cool an all (although where that trackball is, for example, you can't play games like Crystal Castles in horizontal mode), I don't really get having something in the middle of the kitchen. I'd want that deal for its intended use - dish preparation, etc. Then, going by the last picture he posted, if it ain't going in the kitchen, why build it that way?
