Breaking backwards compatability is a hallmark of Apple. They have done 
it countless times over the years. Contrast this to Windows, where 
applications written a decade ago still run without modification on Vista.

I'm still evaluating my options with regards to my own applications, 
which all use Tk-Aqua as their toolkit and therefore are affected by the 
API changes in Carbon. It's my hope that Tk-Aqua can evolve to keep up 
with the API changes, i.e. the relevant parts are migrated to Cocoa if 
necessary. If that proves too technically difficult, however, and 
Tk-Aqua remains a 32-bit Carbon toolkit, then I'm faced with the 
possibility of rewriting my applications (several thousand lines of 
code) in some Cocoa-supporting framework. I'm *not* eager to travel that 
road.
