Apple is selling computers with 64 bit processors that run into a 32 bit

Please tell me it ain't so!

You Apple fans may think 64 bit is unnecessary, but Linux and Windows
users do not agree!
I don't think it's unnecessary at all, and I think Apple is dropping
the ball on this one. I use 3D graphics and video editing software
heavily on and off and 64bit in this area is more than just a buzz
word.
Don't buy Johnson's trolling here. Not booting Snow Leopard in 64-bit
mode on desktop machines by default doesn't actually do anything
whatsoever to undermine the use of 64-bit applications.
Yeah, I know. About the trolling that is.

Apple is simply being pragmatic, and Johnson is playing the usual
Wintroll game of focusing on tech specs and ignoring real world use
cases.
True to form, indeed. But a 32 bit kernel does impose limitations on
the drivers, does it not? I mean, even if it's a fringe case, it's
still a limit.
I looked up some info on the G5, and it said that it could address 8 GB.
It couldn't do that with a 32 bit bus, so the person I responded to
is wrong about that.

What is "it" in the sentence above? I don't know what the G5 has to do
with anything, but apps running on Leopard and Snow Leopard can
address more than 4GB of RAM, in spite of the kernel being 32 bit.

The G5 is a 64 bit processor, so I'm unsure what you are in reference
to with your "32 bit bus" remark.

The limitations a 32bit kernel imposes in OSX's case is for drivers
and kernel extensions.

You have to go back to earlier remarks that have been snipped out for
what I wrote to make sense.

Snit showed I am wrong anyway, the G5 Macs do indeed have a 32 bit data
path even though the processor is 64 bit.

And if you have a chance to educate me about a topic I am wrong about I hope
you take the chance to do so. Thanks for the acknowledgement.
