How can one be fed up with manufacturing capacity at peak levels of human and machine efforts? It takes 6 months to establish a new manufacturing line at a plant like Foxconn and that's only if vendors can supply enough product in that time frame.
It's not like they aren't making well over a million per month (2.4 million as of this month). If problems were held down to just a few hundred thousand, then there would be cause for anger.
WiiFit's production woes could be just the same. The unit uses 4 high end scales. I don't know the vendor for the scales but I guarantee you they've had to manufacture more the past few months than the past decade combined.
Also to consider are that initial retail orders for both Wii Fit (and the Wii itself back in late 2006) were probably much lower than post launch demand meaning manufacturers would have taken that initial retailer demand figure and allocated resources for production based on those numbers. Once launched and demand far exceeds supply, it can be very difficult to reallocate manufacturing resources (that were at that point set aside for other products) to match demand.
There is a lot more to chain of supply than just hitting an increase supply button. Sometimes it means slowing down the production of another companies product to make room for the expansion and that can cause problems.
Keep in mind, Nintendo's loyalty is an earned loyalty. Their customer service has won awards.
