It seems to be typical for Nokias high-end/niche products to have a slow ramp-up. Nokia wants to avoid having a warehouses full of expensive hardware not selling.

It usually works well, but if a product gets much more orders than expected, or there is lots of people who want the device as soon as the device gets to market, the backlogs can get quite long. As the component manufacturers have committed to a certain production rate, it might to hard to speed the ramp-up process.

For most users it does not matter (they get the products via operators anyway, and operators bring their own delays to getting new products to sale), but for early adopters and fans it would be great service to make an initial round of the devices big enough to satisfy all the pre-orders at once, instead of manufacturing a minimal round...
