Actually, no, it's not... it's "slightly better than 720p" It's technically not a standard HDTV resolution. 480, 720, and 1080 refer to the number of vertical scan lines, regardless of i(nterlaced) or p(rogressive). 1080p is visually superior to 1080i because you don't have image tearing during fast motion, as you do in an interlaced picture (where you're painting the even, then the odd scan lines every 60th of a second (painting a complete picture every 30th)
Here's a good question, and one that I am too lazy to look up. NTSC 480i (aka SDTV) has always been 29.97 FPS (double that to get the scan rate). Now that HDTV is digital, did they finally *kill* 29.97 in favour of 30?
Mind you, no content on the market is 1080p, so it's only worthwhile if you plan on using your monitor with your computer (and you are). Good news on that front, as HDMI to DVI adaptors are cheap, so you don't have to ever deal with an analogue VGA connection.
