I think if you have never been to the Super Bowl or a major sports championship (NBA Finals game, etc) then you should always take the opportunity to go once in your life. Especially if you had good seats!
But partying at home is the best for a lot of people.
As for TVs - I have a 65" Hitachi HDTV (not flatscreen) that I have had for a couple years. Plus a 42" Vizio flatscreen HDTV, which is awesome.
Vizio is a great buy right now at Walmart!
