Certainly true.  The problem on the PC side is that it's difficult to
figure out what hardware actually is well-engineered, whereas when buying
a box from Sun, it just works.  It's unclear to me whether, for example,
*all* of IBM's PC kit has quality engineering or if they have some cheaper
stuff for people really looking for a price break....

And even with quality hardware, I'm just not seeing people having the same
experience with PC kit of any type as we've had with Sun kit.

Everything I've heard indicates that Coda doesn't actually exist as a
product.  It's an interesting research project that never became anything
more than that.  Research projects are cool for what they are, but I
wouldn't run an enterprise file system on one.
