Is 720p vs 1080i worth being implicated about? Yes and no. If you're a consumer seeing for a new Tv, you can happily ignore the 720p vs 1080i deliberate upon because every Tv which is described as Hdtv or Hdtv Ready is required to withhold both formats.
Note: You should be aware though that lots of Tvs which withhold 1080i have fewer than 1080 lines and so scale the 1080 signal down. That's not a huge issue as even scaled down 1080i is far ahead of a quarterly Ntsc signal. It is worth bearing in mind that more expensive Hdtvs tend to have better scalers than cheaper ones, and this may be an issue.

However, for broadcasters it's a live issue. Should they broadcast 1080 lines of interlaced video or 720 lines of progressive scan? They could just broadcast two signals, one in each format, but that would use up a huge chunk of bandwidth and be hugely expensive for very little gain.

Which Size HDTV is Right for My Room?
 | With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience. If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.

To respond the question, it's foremost to understand the inequity between 720p vs 1080i. A 720p signal is made up of 720 horizontal lines. Each frame is displayed in its entirety on-screen for 1/30th of a second. This is know as progressive scan (hence the 'p')The capability is like watching 30 photographic images a second on Tv. A 1080i signal comprises 1080 horizontal lines but all the lines are not displayed on-screen simultaneously. Instead, they are interlaced (hence the 'i'), ie every other lines is displayed for 1/60th of a second and then the alternate lines are displayed for 1/60th of a second. So, the frame rate is still 30 frames per second, but each frame is split into two fields, which your brain then puts together subconsciously.
Most of the time interlacing works fine, but for fast engaging images, such as sports like baseball and hockey it can cause problems which manifest themselves as a 'stepping' result on-screen. Progressive scan signals don't have this problem and so are better superior to sports.
Espn puts it like this: 'Progressive scan technology produces better images for the fast engaging orientation of sports television. Naturally put, with 104 mph fastballs in baseball and 120 mph shots on goal in hockey, the line-by-line basis of progressive scan technology better captures the possible fast operation of sports. For Espn, progressive scan technology makes perfect sense.'
Bottom line? For us, as consumers 720p vs 1080i is not a deliberate upon worth worrying about, so you can relax and focus on all the other criteria on your list when you buy your next Hdtv.
