[snip various super-stuff running xfs]
I understand that xfs is great for super-computers[1] and stuff, but how
is that relevant to a desktop computer with something like this?
The background info I provided relating to supers was in response to
Shawn calling my statement of 'quality FS' an 'opinion'. If XFS isn't a
quality FS people wouldn't have been using it on $100 million
supercomputers for over 13 years. And in that 13 years it has seen vast
improvements.

(actually one of those partitions is on xfs, but that's not my point)
The only real downside to using XFS as a primary desktop filesystem is
tool familiarity and knowledge. For the casual desktop user XFS may not
be all that suitable due to this, but any power user will be more than
happy with it. As with anything computer related, one needs to read and
learn about it before taking the plunge. Users who simply select all
the defaults during OS installation need not apply.
Regarding desktop suitability, all SGI MIPS graphics workstations from
1994 onward, including the popular O2 and Octane, used XFS. The CG
effects in almost every movie between ~1995 and 2002 were created on SGI
workstations all using XFS. ILM used SGI workstations with XFS from
1994/95 until switching to commodity AMD Opteron systems around 2003/04.
I don't know what FS they currently use on their workstations today.
Given the size of the data sets I'd bet they still use XFS locally,
though I don't know if they use CXFS on their SAN or another cluster
filesystem.
