How Soon Is It OK to Set Up the Christmas Tree? [SURVEY]

I bought an artificial tree for the first time last year. We were live tree people but last year our tree was toast by Christmas (all the needles fell off). So this year on Christmas Eve I bought a 9-foot artificial tree at Home Depot. It is guaranteed to look great, the needles will never fall off and did I mention I got it on sale? I'm so excited I want it set up for Thanksgiving (we're having the whole family over to our house). My wife says no. My friends say no. What do you say?
