Apple might just feel shockingly surprised at themselves if they achieve SL level refinement.
10.6.8 is still the gold standard for Mac OS stability and refinement. :cool: Of course it didn't hurt that Snow Leopard was touted from the very beginning as "no new features, just improving on what is already there". And that is almost exactly what they did. :apple:

I really miss that mindset.:(

I guess El Capitan will be the first OS in years to go beyond the .5 mark. If that means stability will be up on par with 10.5 and 10.6 releases, then this would be quite astonishing for Apple in 2016.

I prefer the "old" times, a new OS every 1 ½ to 2 years. OS X used to be more stable after the 10.x.5-6 versions.

Joking aside, I agree, although I don't have too much trouble with Mail it's an Application which SHOULD work well.
