WTF!? he said that there's no difference between 1080p and 720p? WTF!? the difference is abysmal! it's like jumping from the SDTV to a HDTV!

480p (SDTV)
-720p (HDTV)
------------
240p

720p (HDTV)
-1080p (FULLHD)
------------
360p!!!!! it's 1.5 times the same jump from the SDTV to an HDTV!!!!

This don`t make any sense...

 

640x480p = 307,200 pixels

1280x720p = 921,600 pixels (614,400 or 3x more pixels than SD) 

1980 x 1080p = 2,073,600 pixels (1,152,000 or 2.25x more pixels than HD)

Your logic is wrong because SDTV is 4:3, while HDTV 16:9.
