mobile

1.   video calling
     without video calling what use is 3g ?
     but many of the low cost mobiles come with just one camera.
     may be they want to save on the cost of the second camera.
     but why cant we think of a swivel camera , which can face you
     when u r on video call and face the object when u r shooting ?

2.  mobile as computer
     mobiles are expected to replace computeres at least in india.
     but what to do for the typing without a proper key pad ?
     why not think of a key board (  rubber based , foldable ) which
     can be  plugged into the mobile thru a  usb port ? so what is
     required is a usb port in the mobile which should not be a big deal .
