That was why C used it, but it leads to uneccessary problems with 
typos, too many meanings for the symbols and overall less legible 
code.

In terms of modelling, "&&" is used for reasoning about control 
flow and "&" is used for low level trickery. There is no usabilty 
advantage in mixing those levels visually. Also, the semantics 
are different as "&&" shortcuts, a point newbies tend to 
overlook...
