I just got my new TV today. I didn't really get it for march madness though. i got a 52" Samsung LCD with 120hz motion which is supposed to make sports and action smoother. We chose Samsung over Sony because we have a Samsung LCD in another room and it works great.
I also got a Logitech Harmony One remote. I got it all set up but my wife was watching something on DVR so I couldn't check it out completely.
The new TV looks a lot better, sitting on my new entertainment console/table than my Sony big screen did. I don't know why everyone at work thinks my wife is the only one responsible for the decorating in my house.
