Not so. The advantage is source compatibility and the unity of OS
environments across architectures. Sun already supports three
architectures with SunOS (Intel, Moto, Sparc); adding a fourth
wouldn't be much of a stretch. Then again, SunOS may be more of a
liability than an asset. (No smiley.)

Right you are. We've been thinking about using Suns around here, but
things are looking good for a move to the 6000 instead. I still
remember Henry Spencer's comment: "It is well-known that Sun's quality
assurance department consists of a single clerk with an IQ of 37
equipped with a rubber stamp marked 'PASSED.'" It can't be a
cooincidence that 90% of all messages in the security mailing list
are about SunOS security holes...
