Using solid state disk

I just got a 40 gig solid state drive as a byproduct of something I
was doing and wonder how to use it.

What file systems work best on SSD? Are the suggestions about
disabling atime worthwhile? Example:

With 40 gigs to play with, and lots of rotating storage as well, in a
desktop box, I'm thinking maybe the SSD gets 8 gigs for / and 32 for
/usr with swap, /tmp, /etc, /var and /home all on hard drive.
Basically, use the SSD mainly as read-only. Is that sensible? Are
there other things I should consider?
