  The market for all such devices is growing and is expected to be around 18 million units by 2005, according to IDC, a market research firm.

https://en.wikipedia.org/wiki/IPod#/media/File:Ipod_sales_pe... shows Apple, with the introduction of the iPod nano, color, and shuffle, sold over 20M units in 2005

Compared to the usual IDC/Gartner et al that is amazingly spot on. Not that a four year forecast like that is easy to do!

When I read that line it made me think... has anyone done any decent comprehensive retrospective scoring/review of their or other industry 'predictions' even in the near future?

Thanks for looking up that info. I was curious to see how accurate these kind of predictions from IDC were. 20M units for iPods alone vs a prediction of 18M units for the entire industry. Interesting.

To be fair, I doubt the rest of the industry sold more than a few million units.
