Well not that you mentioned, I was reading about the 64bit changes
that OS X and Cocoa api has, and how to convert my current 32 bit app
to 64 bit app.
In an apple doc I read that mos of leopard app doesn't need to convert
to 64 bit architecture, but later on the document its says something
like, that in the future the apps should take advantage of the new 64
bit api and frameworks, or that what I understood, so, I was
wondering, if Im starting a new app (small one), should I build it for
a 64 bit architecture or no?, if so what should I take care of?,
instead of using int use NSInteger or NSUInteger, alos instead of
float use CGFloat, take care of the way I encode and decode ? I guess
im missing lots, and what else should I change the build target to be
64 bit architecture?
any guidance? or should I just "let it be, let it be"

So even better, is there a convenient GUI-based way for a user to
check this? I don't see anything in "About this Mac".
Actually - yes. "About this Mac" *will* tell you. If it says "G5" or
"Core 2", and 10.5.*, it's a 64-bit capable Mac. If it's running any
earlier OS release, a G3 or G4, or first-generation Core, it's 32-
bit only.
