Agree with Chscag.
Also 10.6.8 is still not that old and while not really supported
I have to take issue with this statement: as far as I can tell, 10.6.8 is as fully-supported as Lion and Mountain Lion except for point updates (which Lion doesn't get either).
All the latest Apple software works with Snow; by virtual of being all-Intel, it receives the latest Java, Flash, QuickTime, iTunes, security, printer/camera and server updates; it even runs the Mac App Store (and thus almost everything on there is Snow-compatible). About the only thing I think that is really big that Snow Leopard has been left behind on is iCloud, though I'm happy to be corrected on this.
This is the real reason most people think Snow Leopard is so great: it's well-supported, familiar and hasn't been obsoleted as badly as, say, Leopard.
If you have a pre-2009 machine, particularly one with the early Intel graphics chipsets or a hard limit on RAM (like my beloved BlackBook for example), I would be the first to say that Snow Leopard is the best OS for it, and you should stay there on that hardware.
Post-2009, however, I'd have to say that Mountain Lion is the best, and would encourage people to move up to it. Lion had some teething troubles with versions, save as and other changes that were not wholly successful, but that's why they keep polishing this stuff. For security reasons alone, I'd say that if your machine can run ML well you need to be running it.
still new enough so you won't see any major problems with every day usage. Try going back to even 10.5 and you will start to see some sites that do not work right and no way to update to a browser that will work 100%. Go to 10.4 Tiger and the problem is many fold worse![/QUOTE]
