Good points.  Thanks for the feedback.

Of course, it is good to move caches and /tmp to RAM and set the
noatime option in /etc/fstab .  I found more useful ideas here:

Are there other pages I should be looking at?

I used ReiserFS for some systems, but I did not have good luck
with it - it was fast, but it did not handle disk errors well. 
And I worry about my wife's safety with Reiser around :-). 
Your mileage may vary, of course. 

I will have to think about ext2 vs. ext3 vs. "other".  I expect I
will set up a boot partition with ext2 (journalling is not needed
if the files don't change much), and use some solid-state-friendly
file system such as jffs2 for the main partition (or at least
/home and /var).  More to learn...
