B&H regrets your dissatisfaction. We will not tell you how many of any product we anticipate receiving nor when because the assurances of this nature we receive from our suppliers is often optimistic or downright unrealsitic. This thread is now 38 pages long and I'm pretty sure I've said this before here. If (for example) Apple tells us to expect 50 on May 9th and we get 45 on May 10th, but we told you 50 on May 9th, we come off looking idiotic, not Apple. Any retailer who is willing to make assurances of this sort, particularly for a super-hot and difficult-to-obtain product like the iPad 2 is either overoptimistic themselves or careless, IMO.
Likewise, providing some arbitrary "where am I in line" number is equally unwise. First, as I said above, if we assure you we'll get yours on Tuesday and we don't, we look like idiots and second, let's say we do get 50. Everyone of the first 50 in our queue us equally number one. If you're number 50 and we tell you your iPad is coming Tuesday and it doesn't, you're #2.
There are, I believe 18 different iPad 2 models. it would be nice if Apple shipped a boatload of each today, but that's obviously not going to happen. B&H is as eager to get these as our customers are and as eager as our customers to fulfill every order as speedily as possible.
I am sorry for your dissatisfaction and the ire it's caused.
