Huh? Apple frequently releases new hardware that is incompatible with older
versions of the OS. That is because the newer version of the OS has enabling
code to use new hardware. In the bad old days Apple did this with "enabler"
extensions which made the life of we tech support people utter chaos. This
can sometimes be a little frustrating (for example when we try to boot a new
computer with our favorite disk utility and find out that it needs to be
updated for the new computer) but it is no big deal. There's no reason to
make a big issue of it.

Well doh! About 10 years ago Motorola released the PowerPC chip. But that
doesn't mean that old hardware isn't useful. I have a Quadra running as an
email/list server in one client's office and an SE/30 running as an email
server in my wife's office. The older computers don't run the newest
software but that doesn't mean they can't run older software just fine.

I don't know where you people get your ideas! The big deal about Quartz
extreme is that IF your computer has the right video card and enough video
memory THEN QE will offload some of the video processing tasks from the CPU
to the videocard. IF not then the CPU continues to run those tasks. This is
no big deal.

Sigh...you have clearly shown that you don't have enough knowledge to have a
valid opinion on the matter.
