I usually not a big fan of these types of "giant" infographics, usually created by shady Internet companies to generate link bait, but this one is actually informative and pretty well laid out. It brings me back to my very first iPod (3rd generation, 10GB... which I pronounced the greatest invention in the history of mankind) and subsequent iDevices which have had made legitimate impacts on how I interact with technology. With 78% of the MP3 Player market and 350 million iPods sold, I'm guessing it will do the same for many other readers of the site.
We've come a long way since 2001. I guess we're about ready to see exuberance over a first-gen iPod shuffle used as a punchline in cheesy comedy set in 2005 or hipsters ironically using click-wheel monocrhome iPods.
