Sorry, FULL HD is 1080p. 1080i is even worse than 720p since it has less pixels per frame.

Although it does not make much sense to say: "My TV only supports 1080i", it does make sense to say "My favorite channel only supports 1080i". That code is actually missing one important number, which is the FPS.

Some channels broadcast a signal of 1080i/25. This signal is worse than 720p/25. 720p/25 is worse than 1080p/25. (in terms of bandwidth).

720p/25 = 1280*720*25 = 23040k Pixels per second.
1080i/25 = 1920*1080/2*25 = 25920k Pixels per second.
1080p/25 = 1920*1080*25 = 51840k Pixels per second.

The fact that your TV makes up some frames for actually displaying 60 FPS is irrelevant to the discussion.

Besides that, in my personal opinion interlaced video displays funny. I rather see a video in 720p/25 than 1080i/25.

No... Interlaced vs progressive might have a place in what you're trying to say but 1920x1080 is ALWAYS more pixels than 1280x720. More pixels mean higher detail. You didn't mention motion, which is where Interlaced pictures display some problems.
