For camera-based moving material or static
computer generated stuff (not Nyquist filtered), that is true.
I have not seen enough fast motion in 1080@60i to say
what it looks like. I have seen of course converted 1080@50i
fast motion and it looked abysmal, terrible, horrible, extremely bad,
etc., etc., as was discussed. This of course means that Europe
will not be able to send us sports or other fast motion
material, unless this problem ... a really terribly hard one ...
is solved, but the reverse problem (60 -> 50) is not quite so hard.

Then you have the worst of all worlds: a fixed pixel
device that is not a simple multiple of any TV
standard (unless somehow you manage to use
only 720 lines, of course). You cannot use that set
to test 720p vs 1080i, because it cannot
display 720p native unless you don't use 48 lines.
