On the subject of "shortages", these (Japanese) numbers were posted in another thread.

Sold / Shipped
Nintendo DS = 1,657,684 / 1,800,000
Sony PSP = 608,906 / 800,000
This would indicate that there are 142,316 DS units sitting on the shelves in Japan, and that it's had a 92% sellout rate.
While the PSP has 191,094 sitting on the shelves, and a 76% sellout rate.
Of course, Sony has supposedly ramped up their production lately, but still, it looks funny when you see the mainstream media constantly ooohing and ahhhing over the PSP, saying it
must be doing amazing, because it's sold out, while at the same time they just dismiss the Nintendo DS.
