I was looking at upgrading from a 42 inch LCD to a 55 because I saw one in the shop and it looked so big when I was standing in front of it. I thought a bit more about it when I got home. I sit about 3m from my TV and realised that it will look cool for the 1st 5 minutes but it is only a tiny bit bigger really when you are sat that far away.
So I ended up getting an HD projector for the same money. Arrived today. Puts a pin sharp picture on a white wall that is 4 times bigger than the biggest $14,000 TV in the shop.
The great thing about HD projectors is that you can actually see the pixels if you are about 2m away which means 3m away (typical seating distance) is just beyond pixel peeping distance and the perfect distance to take advantage of HD 1920x1080 resolution.
Which brings me to my other criticism of your TV. You have an HD TV and you don't need one. You would have to sit less than a metre away before you make out the pixels so if you are more than 2 metres away then a 6 year old 1024x600 screen will look just as good!
But the coolest thing of all about projectors is that when you have a cigarette it is like going back to the cinema in the 70s and 80s - you can see the smoke weaving and swirling in the light beam... cool!!!
