Someone needs to point HTC to proper information. 29.7 FpS only is valid when you factor in motion blur, which movie/tv does. Computers and thus android do NOT typically. (I've seen no evidence that android does natively in it's OS, but video players DO).
This site has a good explaination of what FPS really means:
How many frames per second can the human eye see?
If we only watched movies on our phones, sure 30fps would be fine... want to play a game or move icons fast.. forget about it.
