What is 720p video recording I heard about the complaint of the Nexus S' lack of 720p video recording? What does 720p mean? How does it compare to the standard Samsung Galaxy S phones?
From Wikipedia:


  720p is the shorthand name for a
  category of HDTV video modes having a
  resolution of 1280×720 (for a total of
  0.92 megapixels or 921,600 pixels) and a progressive scan. The number 720
  stands for the 720 horizontal scan
  lines of display resolution (also
  known as 720 pixels of vertical
  resolution), while the letter p stands
  for progressive scan or
  non-interlaced. When broadcast at
  60 frames per second, 720p
  features the highest temporal (motion)
  resolution possible under the ATSC and
  DVB standards.


The Samsung Galaxy S is capable of recording 720p video from it's rear-facing camera.  The Nexus S is not (max resolution of 720x480).
