But, why? Is the product alone not enough for your money? If you feel so strongly about this, why not wait for it to be released officially before making the purchase?
Google's customer service isn't the issue here. They offered the product for pre-order without making any statements about a shipping deadline. To then turn around and expect them to set one just because you gave them money is foolish.
Google's customer service is the issue here. How a major tech company that focuses on the delivery of data designs a system that can't provide even the most basic of ordering information in 2012 is beyond me. It's what I expect from a small start-up (and even then it would irritate me). Why isn't there an estimated shipping timeline (nothing specific, just what they've also stated in the press, est. 3-4 weeks/subject to change). And why do I have to call to change billing information? I'd expect that from Sears or a behind the times brick&mortar, not the company that has helped define the internet.
I understand there are alot of Google apologists on HN, and Apple get's the lion's share of positive tech press (they also get the majority of negative press too), but they should be pushing Google to be a better company, not insulting first adopters that pre-ordered a Google product.
