People are complaining about the price, I'd assume this is not being aimed at the average joe, just like the overpriced Mac pros , these will be snapped up by creative agencies and major companies by the truckload, except unlike the Mac Pro this device is fit for purpose.
Smart move by Microsoft, go after the professional segment which apple has neglected. And if Microsoft commits to updating this every year, it's a winner, as apposed to its own "pro" machines that get updates every 3 -4 years.
And from my experience, from prior Microsoft products, this thing is only a starting point, by version Three it will be a much better product, miscosoft makes impressive jumps each generation.
