It's nice to know OS X will run on an older machine, what display card
have you got in that machine?

'tis true.

I really haven't noticed any difference running 9.2.2 compared to 9.1 on
my iBook but then it's OS X compatible and runs OS X most of the time. I
think the reason is a lot of the legacy support code has been stripped
out.

It is a great deal faster in OS X, yes.
