I wouldn't necessarily use MacWorld as a reliable guide to processor
design. From hearsay (and I admit its such), one of the drawbacks to a Mac
as a developer machine is that its I/O throughput is horrible, which just
means builds take even longer. Complete Mozilla builds can be compared to
the effort required to lift a facing stone up the side of Cheops' Pyramid
on a reasonable workstation as it is.

That PDP-8 must have been a figment of my imagination then.

I wouldn't get hung up on operating systems too much, it doesn't much
matter which OS it is, the Mac is quite radically different in a lot of
areas, including user expectation of the interface (OS-X
included). Keyboard and mouse arrangements are different for
example. Plus, the availability of OS-X isn't likely to increase the
number of users on its own, though it will make it easier for existing Mac
developers to continue development so long as they are already using X. It
will still be true though that to develop for a Mac, you'll need a Mac.
