while i understand what your saying, i must say that 1080i blows imho!
720p is way better than 1080i, all your getting is two frames of 540 lines of resolution which is why when you see t.v's that showcase 1080i as their native resolution, there is NEVER support for 720p. it simply doesn't have 720 lines of resolution, only 540 lines, enough for 1080i and 480p.
plus hd/dvd and blueray will be 1080p, once again a 1080i display has NO ABILITY to play them at full resolution
but.......beauty is in the eye of the beholder as they say, so...if it looks good to you that's all that matters
