Not a good omen. (Edit: they fixed it.)
Without having seen the product, I'd say that its fortunes will be based largely on its price point. They need to have a compelling offering in the $499 range, or this is going to be a blip on the iPad/Kindle Fire market.
Similarly, there was at one point a vibrant "business mobile phone" market as distinct from the "consumer mobile phone" market. That distinction has been erased, killing RIM in the process. The jury is out as to whether there will be a viable business tablet market. My money says no, that at a significantly higher price point than the iPad, business users will continue to buy laptops.
But this is also, of course, why I posted about the site crashing during the launch in the first place.
The business market seems like it would be a huge opportunity for Microsoft to bring Apple-like technology to the business side. However, they seem far more interested in chasing Apple and Google in the consumer market.
