amije,
Who needs it? People in North America, Japan & Korea. People who have systems at work with little hope of getting upgrades purchased. A lot of non-profit groups, churches, and government agencies.
As for a PAL version? I can't state this as a proven fact, but... Among Toaster users the general belief is that NewTek took other company's video chips and forced them to do things that the manufacturers never dreamed of. Some / many / most of these video chips did not have PAL equivalents. (If there had been, maybe C= would not have gone under.) Do you think NewTek did not want to sell Toasters all over the world?
