The idea that WiMax replaces WiFi is like thinking that 18 Wheelers replace 
private automobiles, or a saw replaces a screwdriver.   That such ideas 
even pass muster in the "press" is a comment on how little the technology 
press understands the technology it covers.  (of course the marketers who 
tell the press how to think are guilty, too - the idea that the prefix "Wi" 
means seems to be "hot new technology that ought to boost the stock price 
like -tronics used to").

What WiMax might replace is coaxial cable or DSL copper, or the fantasy of 
FTTH - certainly the companies that leverage themselves by huge junk bond 
issues to put infrastructure in the ground are vulnerable to a 
high-performance, cheap to deploy, rapidly depreciable alternative.   In a 
stretch it might compete for 3G's slot in the world (if they change the 
underlying physical layer to compensate for 60 mph mobility).
