Great question.
Phase One has hit their first promised milestone of shipping units by May.
The press release stated ...
"Availability and Pricing
The Phase One IQ180 is expected to be available end of April 2011. The Phase One IQ160 and IQ140 are expected to be available end of May 2011."
shipping a few "production" backs to dealers doesn't seem to qualify as "available" ... maybe they changed their tune later to dealers to state the new goal of shipping units by May, but seems like they've missed the mark a little based on the press release. Of course, throwing the word "expected" in there sort of clouds things
Despite that, I know they are a small company tackling difficult technological challenges both in design and manufacturing resources, so I'm optimistic in that while maybe not literally hitting the mark, I would agree with you that in many ways they're ahead of or at least close to what most expectations were. I also have a couple of major shoots planned 2nd week of June so based on current information I'm at least somewhat hopeful ...
