the two are comperable in that WAP applications compete with 
traditional Internet applications, and people will sometimes
have to choose between "native Internet" and WAP as a means
of running their application (or support both)

sure, but SMS was the limiting case on the bandwidth side.  were it
not for the need to support SMS it would have made a lot more sense to 
just use IP. (though not necessarily to use traditional IP transports or 
applications on top of it - but that would have at least been possible 
for those who were willing to suffer the expense/delay.)

display size might not have been a fundamental design constraint
of WAP's lower layers, but WAP applications are certainly designed 
to cope with limited display size, and the limitations of cellphone 
displays are often used as a justification for using WAP instead 
of IP based applications.

today, perhaps.  tomorrow is different.

an industry that believes its own marketing propaganda is quite often wrong.
