Are we likely to see large screen flat panel t.v.'s in the short to medium term at an affordable price? I'm not talking large as in 42" Plasma (which of course would be nice), but 28" to 36" size wise. What if any are the limitations to size in the current generation of flat panel t.v.'s. What are the pros and cons of Plasma versus Flat Panel? Genuine responses would be nice - hope I'm not opening up a can of worms with this one.
