Well, I have installed FC3 that way (XFS on most partitions)

It's best if there's a match between the tools and the purpose.
XFS was designed first and foremost for performance. Clean behaviour
in the case of sudden loss of power to the processing unit is not
exactly a high-priority design constraint for systems such as
these...

...since the processing unit is always behind at least one layer of
backup/redundant/uninterruptible power supplies.
However, the highest performance possible is one of (if not THE)
most important design constraints.
Another assumption behind XFS is that storage is the best quality
and therefore it does not lie when it reports back that the data
was flushed all the way to the magnetic layer (which is something
that cheap IDE drives/cards lie about, sometimes).
Bottom line: use Ext3 for the general-purpose partitions. Use XFS
for your MythTV partition, or the one used to do video capture, DVD
backups, ISO images, etc.
At least that's what I do.
