for many things, 32bit code is more compact and runs faster than 64bit 
code (primarily because the code is smaller, so it requires fewer 
fetches, more code fits in the cache, etc).    64 bit OS's totally 
compatible with 32bit applications.  of course, if a process needs more 
than a couple gigabytes of address space, then 64bit is a no-brainer, 
but there's really not that many applications which need that sort of
