Here's the perfect cnet article for you (1080i vs 1080p)
1. 1080p defined
1080p resolution--which equates to 1,920x1,080 pixels--is the latest HD Holy Grail. That's because 1080p monitors are theoretically capable of displaying every pixel of the highest-resolution HD broadcasts.
2. Why 1080p is theoretically better than 1080i
1080i, the former king of the HDTV hill, actually boasts an identical 1,920x1,080 resolution but conveys the images in an interlaced format (the i in 1080i).

1080i (plus some 720p) is mostly what is being boadcast or carried on HD cable. Most HDTV sets receive 1080i but display at some lower resolution.
1080p is the top of the line for display, but is not currently being broadcast. 1080p capable TV sets cost $5k up ($4k up for DLP projection) but will come down in coming years.
1080p will be supported by the next generation HD DVD players.
Best Buy had a 37" Westinghouse 1080p LCD monitor for $1500 or $1800 on Black Friday. I don't think too many bought one though because there isn't a use for 1080p yet, at least that I have heard on the consumer end.

Added: I guess this is it. I would be concerned about only 1000:1 contrast for home theater application.
Yup, it was only in certain markets for $1499.99 and it is 1080p native. Me, I wouldn't go near an LCD.His name was MackemX

Sounds like the marketing strategy is to co an apples and oranges comparison.
I quickly saw this set at Sears a few months ago. It looked really nice. Sadly when I walked in I asked the sales guy if they had any 1080p sets and he had no idea. He said he "knew the basics and anything else I could look up online". Idiot.
Anyone know more about this set? Being DLP does it have the problems mentioned above?
I'm also a little worried about bulb life. My set runs around 16 hours daily everyday now.
Bulb life at that rate looks like a couple of months.

1080i is 59.94 fields per second (29.97 frames per second). This is what is broadcast.
"line doubling" will interpolate the missing lines from field 1 using a combination of samples from field 1 and field 2 and field 1 minus 1/60 sec and field 2 minus 1/60 second. And it will do the same to field 2 so the result is 59.94 frames per second (or 1080 progressive).
So bottom line, "line doubling" does double the lines in each field.
The marketing hype adds "producing 4 times the resolution of traditional line doublers". I guess they are assuming traditional line doublers only had 960 horizontal pixels or equivalent.
To be clear, 1080i (or 720p) to 1080p is an upconversion. 1080i needs to add artificial motion detail, 720p needs to scale size.
Out of curiosity, is PAL 1080i equivilant to 1080p for movies and US tv shows?
Ok so if i were to buy a tv today what do I want for best picture/experience
1080p or 1080i?What We Do In Life, Echoes In Eternity....

In the process, a 1920x1080p/24 database is maintained for release to television and High Def DVD (future Blu Ray and HD DVD releases will be native 1080p/24).
TV networks order 1920x1080i/29.97fps (North America) or 1280x720p/59.94fps (North America) or 1920x1080i/25fps (PAL areas) tapes for current HDTV broadcast.
DVD publishers order 720x480p/23.976fps (North America) or 720x576/25fps (PAL areas) for current DVD relaease.
1080p to the home:
This will happen with the release of the BluRay and HD DVD formats. The data on the DVD will be native 1080p. Player outputs will be 1080p, 720p, 1080i, 480/576p, and 480/576i digital (HDCP encryption required) or analog 480/576p or 480/576i (like current DVD*).
Nobody is broadcasting 1080p/24. The USA ATSC standard permits 1080p/24 and tuners are eventually required to receive it but this is unlikely to happen for many years in reality.
So why buy a 1080p HDTV?
1080p will be the highest home resolution for some time. The only likely source for 1080p will be the future BluRay and HD DVD players.
A native 1080p display will require everything else (e.g. 1080i, 720p, DVD, NTSC/PAL, etc.) to be upconverted. The overall experience will rest on the quality of the internal upconverters for everything except viewing HD DVD. The quality of the first generation upconverters is likely to be poor to OK. As time goes on, upconverters will improve. Also, the price of 1080p displays will drop sharply.

There is talk of a compromise at 540p (quarter resolution of 1080p) for analog component viewing of HD DVD discs.
I consider myself somewhat of a smart guy, but even trying to figure out the ins and outs of TV's is getting ridiculous. We should be able to go in a store, say "hey, I want a TV that can play HD". Sure... they all do. Not this well... what's your native resolution? do you want it to upconvert?... blah blah... too many damn nitpicky things. Just make the picture look good.
