New iPod Nano
If the new iPod Nano, supposedly to be unveiled on Sep 9, doesn't look like the pictures on this web page, this 3rd party iPod case manufacturer is going to have a lot of wasted inventory (another leaked photo via Engadget seems to echo the previous photos).
I use my iPod all the time, but it's harder to get excited for every next iPod release. The differences from one iPod Nano to the next aren't that significant anymore; they tend to center on greater storage for the same price. The major form factor benefits have been realized.
Not that there's still not huge revenues and value to be extracted from the iPod line. Google's search ranking algorithms haven't noticeably improved (to my eye) for many years, but they continue to rake in cash because no competitors have been able to leapfrog them.
