It *really* winds me up that we never bother to test this hardware before we ship it.
But I'm even *more* disappointed that we can't even diagnose it and publish coherent errata *after* the fact. I'd really like to see each quirk which disables features referencing a specific published erratum. We really ought to be able to manage at least *that* much.
