The most recently available Macs that are 32-bit only, the Core-series 
Mac Mini, were shipping a hair over 4 years ago.

The first generation of Intel-based desktops used the 32-bit-only Core 
processors.  The last model to switch to the 64-bit capable Core 2 
processors was the Mac Mini; the announcement of the new models was made 
on August 7, 2007.

I don't know if this information will affect decisions (I personally 
prefer 64-bit by default) but I thought it best pipe up, just in case.
