Defenders of Apple's monopoly offer hard-to-test claims, but many boil down to the idea that Apple's product is inferior by necessity. This will, in turn, cause developers to skimp on testing for Safari, making it inevitable that browsers based on WebKit and other minority engines cannot compete. Or so the theory goes.

We're now testing container hosts in production on btrfs, instead of ZFS. Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). In a test environment, I've seen several more Linux panics in the past three years.
