Apple's best and brightest must be working on 10.11 alreadyWe need a Snow Leopard type of release for next year. Yearly OS updates are gradually lowering the quality of OS X.
"gradually"? I think the slope is pretty steep.....especially given the fact that Yosemite was the first OS X version in a long time to have a large public beta period. It should have been released with very few issues given the amount of outside testing performed.
