HD Questions 720p vs 1080i

Until the content I mostly watch is in 1080p isthe time I will buy that type of display. I think we are quite a ways away from that (seeing as TV has a while before they reach that point)
I get 1080p from quite a few sources. HD-DVD, BD and satellite (although some of the material is said to be 720 and a lot of it is very poor so can't really tell). I don't watch 480 that much anymore, plenty of HD material available out there. -
...So if your source is 1080i and your display is 1080p, you're getting the full 1920x1080 progressive image.
Like Sami mentioned earlier. If you send a 1080i signal to a 1080p TV, you have all the information necessary to get 1080p displayed. 1080p is just 1080i deinterlaced. It depends on how well your tv does the deinterlacing, but you likely will not be able to tell the difference between a 1080p source and a 1080i source being displayed on a 1080p tv. Soooo, if you are going for a large tv (over 50" in my book) it does pay to go with a 1080p set because of the availability of 1080i signals. Dang that sounds confusing.AVR: Pioneer VSX-84TXSi (RIP - lightening) / Amp: Sunfire Cinema Grand / Klipsh R-10B Sounbar, LC65fx / Sub: Elemental Designs LT/1300 / TV: Panasonic TH-50PH9UK /SIZE] -
720p displays are going to disappear eventually from the market. The jump from 720p to 1080p isn't as much as the jump from 480 to 720 but there is still quite a big improvement in PQ when viewing HD-DVD or BD. Definately not hype but I don't think I'd personally buy 1080 over 720 in 50" displays or less, unless there wouldn't be much difference in price.
I disagree. The jump in PQ is the same from 480p to 720p as 720p to 1080p. The relative increase is in resolution is exactly the same. -

OK, well take HDdvd out of that now... leaves you BR and how do you get 1080p through sat ? it's all 720p or 1080i so again most is done in 720p... -

That's the statistical increase in PQ, not necessarily the perceived increase. I just got 1080p FP and on a 116" screen it's a treat, definitely a huge jump in PQ over my old projector but it's better in all aspects, not just in resolution. On my 61" 1080p's it's not so drastic as going from 480 to 720.
Oh well, it is a definite improvement so if you can, 1080p is a good choice. There's nothing wrong in 720p either, it's still damn good. -

I still watch plenty of HD-DVD's, the war might be over but there are still plenty of movies available that I haven't seen. My satellite gives out 1080i only, which is the same as 1080p in practice, but whether it's upconverted or native 1080i I don't know. Some of the channels are quite poor, and even if it was 1080i the horrible amount compression they apply kills the PQ anyway. -
Well there's two very different issues we're talking about here and I'm not sure which the OP is asking about:
1. 720p versus 1080i SOURCE
2. 720p versus 1080i DISPLAY
On the former, I think it depends on the size and capability of your display.
On the latter, given the same screen dimensions and other aspects being equal, I'll take 1080i. -
I think I already touched the subject earlier; display vs source. In regards to #1, there isn't much to be gained by 1080i source if your TV only can show 720p, but 1080i source certainly is not going to be any worse than 720p source. If your display is 1080i or 1080p then it absolutely is going to be better than 720p.
