First, since I didn't actually get to
install Leopard, I can't comment on speed differences. But I
can state that a Shutdown or Restart is faster! Mainly because you now have only 60 seconds to cancel that request instead of 2 minutes in Panther/Tiger!
Have noted another change in the Finder's Edit menu, the "Compress" item has replaced "Archive." I suppose that is less confusing to noobies?
And, contrary to what I thought I had read, there is still a "Page Setup..." item in most app's File menu. The changes in how one accesses printers has been noted elsewhere.
Are there minor changes like the above that may have surprised you or that make things easier to understand or more helpful?
Enquiring and tediously searching minds want to know!
