Samsung Galaxy S III.....what it the point????

In todays Information Week daily update I was forced to read about the new Samsung Galaxy III that will compete with the iPhone and other smart phones.  Personally I don't see the point in it competing with other smart phones.  For people that love large screens this phone would be great because it is like a mini HDTV, but phones now are meant to be small and sleek and this thing is borderline brick.  I don't know why someone would want a screen that is so big that the phone almost won't fit in their hand.  Also i don't know what the point of anyone competing with the iPhone anymore.  I mean if you go by apples record breaking sales figures for last quarter and who has what in the mall you will see that 9 out of 10 people have iPhones.  With the incompatibility of ITunes and windows media it would be a real pain to reformat all of your music to work on your Samsung Galaxy.  You will have to make the decision on what phone to buy, but I don't see the point of these new so called competing smart phones.
