Interesting...
My wife undoubtedly would like a huge house, but as I do 90% of the cleaning and all of the yard work, I am totally against that.
One thing we would both like though is a state of the art kitchen (mainly for her, but I do cook once in a while), I would like a big yard, a fire pit, a nice deck w/ my grill and most importantly a study.
My study must be large enough for my computers, a couple floor to ceiling book shelves (oak), a leather couch (for reading), a chess table, and a desk and my posters of places I have traveled to - Grand Canyon, Isle Royal etc. However the lighting is one one of the most important features it must be enough to do my work, yet not overly bright - flourescent lights are unacceptible. The final touch is that it is my room, the wife and kids can have the rest of the house, but that is mine.
The kicker would be a large basement with a ping-pong table, a couple of couches, and an entertainment center w/ dvd player, stereo, tv, and my 8-bit nintendo. However I would toss this out if I could have the study.
Addendum: reading though the article and responses, these also struck me as important...
Proximity to work (I prefer to bicycle), a playroom for my kids (could double as my ping-pong room?) and a excellent school district.
