When I bought our 46" TV a couple of years ago it was a good deal at around $1,100 and the 52" sets were in the $2,000 then. Now I can find many 55" TVs for right at $1,000 and 60" ones for under $2,000.
I still don't see why the TV manufacturers aren't making a big push to incorporate ITX, or similar, based PCs into the sets they sell. The cost should be minimal to them and it would give many people a good reason to upgrade their TVs. Instead they try and entice people with 3D sets that don't deliver as advertised, IMO. Show typical person that their large screen TV can basically an all-in-one computer and it will get their attention.
