Here is the result I want to share with APPLE lovers.
1) Cost/Performance: Everybody wants to gain more with less money.
2) Speed: Nobody wants to waste too much time waiting.
3) Profile: Of course we want our software can convert all kinds of video formats.
4) Personal Demands: For example, someone just wants to convert part of the DVD video, or others want the special output video format like PSP compliant forms and etc.
5) Easy to use: we want to make things easy.
Concerning the above factors, I've selected five iPhone converters for reference.
