Use TraditionalForm[].

You can use // TraditionalForm as a postfix.

This will also render Sin[x] as sin(x) etc.

You can also set an option to show all output in Traditional form. The  
right bracket for these cells are shown with a dashed line (on my  
system at least).

I have seen some authors use TraditionalForm exclusively for output. I  
prefer to operate mostly of the time with StandardForm[], which is  
less ambiguous and which is easier to turn back into InputForm.
