The first question is of course what do you *mean* by a string 
datatype?  What type of operations do you intend to do on these 

Binaries provide efficient storage of bytes and with the new bit-syntax 
you also get quite a good interface to access binaries.  There are some 
things to watch when building but otherwies it works well.  However 
there are not many libraries to do the same type of operations on 
binary strings as for normal list strings.

One thing to remember though is that most of the low-level i/o modules
and functions also accept lists of bytes and binaries for output so it
is practical to use different handling for different parts of a message.
For example I can pull apart a binary message, process the wrapper, pass
the data straight through as a binary and recombine it on output with a
new wrapper.
