You guys. Seriously. Get with the HD trend, and know the facts. "720" and "1080" are the widths of the resolution in pixels. So, YES, there IS a difference between the two. Mathematically, 1080p is [more than] TWICE the resolution of 720p.
720p = 1280x720 (in pixels)
1080i or 1080p = 1920x1080 (in pixels)
1280 x 720 = 921, 600 pixels (~1MP)
1920 x 1080 = 2,073,600 pixels (~2MP)
2,073,600 / 921, 600 = 2.25
So, 1080p contains 2 and a quarter times the resolution of a 720p screen.
I've upgraded laptops this year, and I went from a 1280x768 (better than 720p) to my current 1920x1080 (1080p) resolution screen, and the difference is INCREDIBLE. (well, technically, two and a quarter times better.)
P.S. the "p" stands for progressive and the "i" stands for interlaced. Progressive is better. Trust me, it just is.
