I didn't get any notification emails, and from what I read I'm not the only one.
What I find baffling is - why would HP build more? As we have commented before, the screen itself is worth around $90. They will be building more units at an additional huge cost to the company. For what? To satisfy unhappy customers? - like I said before, if these people wanted one they would have bought one when it was $500.
Just for good PR and marketing? I would say that is a very costly and inefficient campaign. Even if everybody gets one, they will still bitch that HP sucks for stopping support of webOS etc.
Yes. Marketing expenses. Customer satisfaction. Increasing market value for webOS in the event it is sold on, or they are trying to push it to other hardware manufacturers.
