some applications(or programs) doesn't have a amd64 version , this is
the major reason.
Still some people(like me) learn programming ,it's a better way to use
i386 , 'cause many books
in the world(I mean as textbook) refer to i386 , such as pointer is 4 bytes.
actually if the cpu arch is amd64, you can install a 32bits system,
and run the 32bits programs , directly .
but if you install a 64bits system , you cannot run 32bits programs
directly ,'cause they link to different libraries.
Though some technique have emerged to run 32bit codes in 64bits system .
