Nice comment, I agree with most of it but there is a little problem in part of it. The endian issues are not that simple. The PPC *can* work in both modes, the x86 can't. On a little endian machine, you wouldn't be able to integrate native and emulated libraries the way it is done in MOS and OS4 right now, ie. you can just drop a 68k lib and it works in both 68k and PPC apps, without using endianess switching everywhere. All legacy code is big endian while native x86 code is little endian.
To everyone else: Don't start lecturing people about x86 hardware, most of us *ARE* PC users apart from Amiga users. I might only have a Pegasos here (running Linux at the moment, for Uni stuff) but I've got 3 PCs back home, all of which built by myself.
