For Mercies SAKE is my Macbook finally going to stop whining like a starving baby after this update?!

 

Come on Adobe! When are you going to stop only supporting 32-bit and move on to a performance level which is 64-bit. I'm saddened this upgrade effort didn't include the "Square" deal. A lot of folks were hoping this upgrade would include 64-bit support. Please provide 64-bit support for folks who don't want to remain "old school".

 

Exactly what is this 'performance level which is 64-bit', all it will do grant access to >4gb memory which flash doesn't need anyway, and any performance enhancments will be so minimal they won't be noticable.

 

It's more than just that. There are a lot of benefits in using 64bit (wiki 64bit for more details), but in terms of pure performance there is almost no difference just as you said.
The most important aspect of a native 64bit flash player will most likely be less bugs and crashes (but only if they do it right) when running on a 64bit OS.

 

Anything, 32-bit or otherwise, will have less bugs when coded properly.
How well something is programmed and how many bits a program is are two mutually exclusive things.
