I have both my macs running 10.5, and am happy. The second best upgrade I have done in as far back as I can remember (Fedora 7, and RHL 7.3 were 1 and 3).
Many nags I had with OSX were resolved. The only thing I havent figured out yet (moreso a time limitation), was howto tweak those stacks around and create new ones.
Time machine is great, as is spaces. The new Mail.app and iCal are nice too. Major update, hell no. But alot of nice refinements. In my past, the major upgrades are always problematic, but the cleanup ones are always the best. Get what should have been working fixed -- and thats what apple did for the most part. Gotta sell it with the new crap (spaces, if it can be called NEW, stacks, time machine).
All in all worth the $200.
