Incorrect as well. 1080i provides 60 lower resolution images per second, 720p provides 30 higher resolution images per second.
Friend, come on. If we're going to talk tech here, then let's talk tech but please don't patronize me, I'm not stupid. If you're worried about the picture quality difference between a 1/30th of second and 1/60th of a second, then I never want to come over to your house to watch anything.
There is no resolution loss between 720p and 1080i. It's the same amount of information except 1080i is split in half to better capture motion which is more of a concern when actually shooting whatever is being produced than viewing it. Once shot and posted correctly you could watch 1080i shot footage on a 720p screen and not know the difference.
Now if you want to talk 1080p or correctly shot 4K footage, then we'll have something to discuss.
