As for media players iPod (he hadn’t called the iPod classic — this retronym the device will receive in 2007), then in September 2006 came only a minor update of the fifth generation appeared on the market in 2005. In the line was still in fact two devices: hard drive 30 GB, as before, and 80 GB instead of 60. In addition, we increased the battery life. Otherwise, the iPod remains the same: with 2.5-inch display, whose resolution was 320×240 pixels.
