  I couldn't give a damn about supporting unfinalised
  standards the ACID3 tests
MS too sometimes speaks of Acid3 in dismissive terms as having little relevancy. Let's see and then decide by yourself, is this stuff important:

  DOM2 Core
  DOM2 Events
  DOM2 HTML
  DOM2 Range
  DOM2 Style (getComputedStyle, …)
  DOM2 Traversal (NodeIterator, TreeWalker)
  DOM2 Views (defaultView)
  ECMAScript
  HTML4 (<object>, <iframe>, …)
  HTTP (Content-Type, 404, …)
  Media Queries
  Selectors (:lang, :nth-child(), combinators, dynamic
  changes, …)
  XHTML 1.0
  CSS2 (@font-face)
  CSS2.1 (‘inline-block’, ‘pre-wrap’, parsing…)
  CSS3 Color (rgba(), hsla(), …)
  CSS3 UI (‘cursor’)
  data: URIs
  SVG (SVG Animation, SVG Fonts, …)
(Taken from: http://www.webstandards.org/action/acid3/)

Looks important to me.

CSS3 isn't a finalised standard, and the test only tests a few things. You do realise there is a lot which this doesn't test too right? That's why some browsers took so quick passing ACID3 (because they focused on fixing the cases tested by ACID3 only)

And as mentioned, one of them is a speed test which is affected by external circumstances.

I'm not saying its irrelevent, but I am saying that a 100% pass rate doesn't mean its 100% compliant with the things being tested. Furthermore, we shouldn't be punishing companies which aren't willing to implement support for standards which are drafts.

ACID2 was genuinely useful because it was all finalised standards. ACID3 though I think could have done better.. So its nice to pass, but a 100% pass just says you are compliant with 100 tests. I'm betting the compliance testing suites used by browsers are a LOT more comprehensive..

That's exactly my point: Acid3 test the important bits, the parts of the spec which are useful. This test is web apps oriented (hence a strong focus on DOM manipulation and dynamic behavior) and thats where web is heading now.

    ...
    HTML4
Saying HTML4 is important in reply to a comment about unfinalized standards is a bit of a non sequitar, no?

Personally, no, I don't give a damn about SVG, but I'd be pretty upset if my browser didn't support iframes. Does the Acid3 test weight its tests appropriately?
