I've had an opportunity to examine a neighbour's large-screen CRT. It's 
an older unit, bought at a time before LCDs were available at that size; 
similar sized plasmas cost as much as the GNP of a fair-sized nation at 
the time.

According to the owner, it's so heavy that four men were needed to get 
it into position. Getting at the back to read the compliance plate is 
out of the question. According to the owner's manual, it consumes more 
than 200 watts.

Though nominally a 32 inch screen, a tape measure shows a viewable 
diagonal of less than 30 inches. The aspect ratio is 4:3; a letterboxed 
widescreen display measures just under 26 inches diagonally.

Comparing like with like between different technologies on the basis of 
viewable area isn't easy.
