Is 720p vs 1080i worth being involved about? Yes and no. If you're a buyer 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 regular Ntsc signal. It is worth bearing in mind that more high-priced Hdtvs tend to have best scalers than economy 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 high-priced for very petite gain.

3D Technology Checklist
This product is 3D-related. To help you get a great 3D experience, use the checklist below to ensure you have everything you need. 3D viewing requires:
 | A Display First, you'll need a 3D-ready display--whether it's a 3D HDTV, 3D projector, or 3D computer monitor. These displays have more processing power than standard 2D models for displaying 3D images in rapid succession. |
 | A Source Your display may be ready for 3D playback, but you'll still need a device to read 3D content. This can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3 system. |
 | 3D Content 3D content--the actual entertainment, in other words--will be played back using the source mentioned above, whether it's a 3D broadcast from your cable provider, a 3D Blu-ray Disc, or a 3D video game. |
 | 3D Glasses For now, the vast majority of 3D HDTVs require glasses for 3D viewing. Many use powered "active shutter" glasses, others polarized "passive" glasses. You'll need one pair per viewer, and they'll have to be compatible with your display, whether they're the same brand, or a pair of "universal" glasses designed to work across brands. |
 | HDMI Cable To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a high-speed HDMI cable. Cables with this designation feature bandwidth speeds up to 10.2 Gbps (gigabits per second), for carrying the 3D signal without any loss of quality. |

Samsung's D490 series makes a great entry-point for 3D Plasma HDTVs. With a 720p resolution, an ultra fast response time, and 600Hz subfield motion technology, you get a crystal-clear image. Connect a USB flash drive to enjoy some video, music, or pictures. Better yet, add a Blu-ray 3D player and some Samsung 3D glasses, and you'll have access to ultra-immersive 3D entertainment.
Make the Most of Movie Night
Plasma Display
Samsung's Plasma HDTVs deliver all the bold contrast and color of plasma, with the advanced features and design that Samsung is known for. Compared to other types of displays, Plasma offers high contrast ratios, gorgeously saturated colors, and allows for wide viewing angles, so every seat in the house is a great one.
3D Picture Performance
See how 3D HD movies and sports come alive with depth and action that leap from the screen. Connect a Blu-ray 3D Player or other 3D device and enjoy an immersive experience (Samsung active 3D glasses required, sold separately). The processing can even be applied to broadcast TV, gaming content and legacy DVDs to automatically convert 2D viewing into 3D in real time. If you’re not in the 3D mood, you’re back to watching one of the best quality HDTVs on the market with the push of a button.
600Hz Subfield HD Motion
For TV shows and movies, 600Hz subfield motion technology renders even the fastest-moving scenes with the utmost clarity and precision, so that each detail is crystal-clear. 600Hz subfield motion is a measurement for comparing Plasma pixel response and screen refresh rates to that of LCD/LED displays.
"Plus One" Design
Samsung's Plasma Plus One Design sets this TV apart, with a bigger picture and a narrower outer frame, for an extra inch of screen compared to similarly sized competitors' models.
Ultra-Fast Response Time
A fast .001ms response time optimizes fast motion video content. Because it can track fast-moving images without motion blur, plasma is ideal for watching action-packed sports or playing video games.

To rejoinder the question, it's foremost to understand the unlikeness 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 appealing images, such as sports like baseball and hockey it can cause problems which manifest themselves as a 'stepping' consequent on-screen. Progressive scan signals don't have this question and so are best powerful to sports.
Espn puts it like this: 'Progressive scan technology produces best images for the fast appealing 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 best captures the potential fast activity 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.
