There’s been some discussion lately about the utility or otherwise of keyboard shortcuts, after Tim Bray linked to several pieces by Tog on the topic. Tim disagreed with Tog’s analysis, leaving explanations as an exercise for the reader, and Kevin Scaldeferri, one of his commenters, took up the challenge:

There’s been a minor furore lately about ZFS and Mac OS and laptops.

First, AppleInsider reported that ZFS would play a larger role in future versions of Mac OS X. MWJ took that article to task, contending (once you ignore the snarky asides) that ZFS is inappropriate for laptops. Drew Thaler, previously a filesystem engineer for Apple, chimed in to extol the good qualities of ZFS.

Then MWJ responded, explaining their position in more depth. Which is all well and good, except that some of the things they said made no sense at all.
