We’re used to shortages during the holiday season. The Wii comes to mind. And you are probably aware of Amazon’s kindle situation. The iPod may be next. Word is that Apple is having trouble keeping up with the demand for the iPod as more and more customers place purchases during this holiday season, they may run out. The information comes from a research note from Kaufman Bros. analyst Shaw Wu. The Amazon.com stock levels seem to confirm the notion as well, since it currently takes up to 5 weeks to get your 8GB second-gen iPod touch. It’ll take 3-5 weeks for the 16GB version.

It looks like the shortages may be model specific and color specific, as some are more popular. Wu concluded that Apple may very well sell 21 million iPods in the holiday quarter.

If you find yourself wanting an iPod that is in short supply, you might want to check out the Sansa Fuze as one decent alternative.
