I agree. And RAM is not the only interest for x86_64 archs, softwares 
can also benefit from more (if not all) instruction sets and internal 
registers of processors.
Some people think that this may improve performances of some softwares, 
or move their limits a big range over if they have been written with 
portability in mind. Max usable amount of RAM is only *one* of those 
limits.

So, for processors able to support x84_64 archs, use it. Why would you 
use only a fragment of your computer's power?
