A reply that i totally agreed with.
Used both phones first, then you'll know the difference.
If any of you wanted to argue about trend. Then answer me this; why did the other brands copy the design/hardware of the iphone? How bout the big touch screen with less button? Side scrolling menu? Pinch to Zoom?
It's okay, take your time to do the research and come back.

Finally, the costs both phone takes to be made.. I mean, come on, who cares? You got yourself an assignment from your lecturer, he/she don't gives a sh*t about how much effort that you've dedicated, but only wanted to see the end product. If it's good, they'll love it, if it's not, REDO + FAILED. Nuff said.
