The Zappos terms of service are materially the same today as they were on a copy I found placed in May 2011 by the Wayback Machine.
I thought that was odd, because, from reading Goldman's and WSG&R's analysis, I'd gathered that Zappos' assertion that it could change the terms at any time - without notice - was fatally flawed.
But then I thought, maybe Zappos deliberately left the terms as they were, knowing it might cure the defect by a change in the shopping or ordering process. The browsewrap language - "ACCESSING, BROWSING OR OTHERWISE USING THE SITE INDICATES YOUR AGREEMENT TO ALL THE TERMS AND CONDITIONS IN THIS AGREEMENT, SO PLEASE READ THIS AGREEMENT CAREFULLY BEFORE PROCEEDING" - might still be in the terms, but if a link to the terms and an "I accept" button were placed so as to interrupt the flow somewhere, anywhere, before finally placing an order, well, that process roadblock would turn the ostensible browsewrap (likely not enforceable) into a clickwrap (likley enforceable).
It seems to me that Zappos' terms are just as open to challenge by new users today as they were before.
