Does what it says with a simple, large button. Couldn't be more straight forward. Plus, its free :)

Just keep in mind that if you enable the 64 bit kernel, any programs that install .kext (kernel extensions) files will not be functional unless they have 64 bit support. (These are things like keyboard drivers and whathaveyou)

Cool. I guess "64-bit enablers" will be the shovelware cache cleaners and "cpu speed accelerators" of the Snow Leopard era.
