We have seen this time and again. We've seen it with the silkscreening, with the black painting, with the keyboard layout, with...
OK, here goes. On the whole, people who have ordered a Pandora do not hate the idea of other/more Pandora owners. They don't mind the idea (mostly - with a very few exception) that other people will, later, get more than they did, earlier. But where forum-going Pandora re-pre-orderers tend to draw the line, and get agitated, is if it looks like they will have something - ANYTHING, however small, taken away from them which they believed they would get.
It doesn't much matter what the thing is. The mathematical chance of receiving a faster-than-average Pandora? The ability to produce THIS character or THAT character quickly/easily? A Pandora in the hand rather than in the bush? A mains power supply? Some clear indication/recognition/sign on their device that THEY helped the project even happen... that they were IMPORTANT, that they weren't Johnny-come-lately "customers" who purchased after the project no longer needed such support? That they KNEW The Beatles personally, before they were famous? These and others are things that people have taken for granted and then been shocked when, AFTER taking the money, OpenPandora have said "You know - maybe you don't need that. We're thinking of not giving you that, or at least not as much of it". That gets people saying "But I WANTED that and I PAID for it - years ago!".
That is all. For the most part, they'll encourage more sales, more customers, a larger community, more software, more more. More is good. They just don't want to lose anything they've already paid for - even if it is "out of spec" and has only been mentioned on the forum, not the official web site. The need for melodrama is largely absent.
