I guess I am a little negative towards because iPod classic lacked FM radio and the more expensive bigger models lacked an EXTERNAL SPEAKER! While ths cheaper iPod nanos did get them and a camera. I sometimes hated listening to just my songs and with only headphones. I had to use PSP to play my songs externally and it was soft.
It also started the trend that influenced smartphone industry with sealed batteries and no expandable storage. And what's with the mirror finish, scratch prone rears? This is why I am not sitting and reminiscing about it fondly like some here since its legacy is not something I was always happy about.
But if I could reminisce the good parts and avoid sounding like a Debbie Downer...
+ Great marketing see below. The silhouette ads especially the one with U2's "Vertigo" basically made me buy their album.
+ My start for greater design in gadgets since I rarely cared before it. Well, PSP helped with it too a few months prior.
+ Made me appreciate great packaging.
+ My iPod video got me into watching LOST because I bought the Pilot episode to check out the video playback. Subscribed to their weekly podcasts soon after and bought a few more LOST episodes after that.
+ I used it when I traveled to Europe twice in 2005 and 2006. In most of my photos, I can be seen with those white headphones on. Even a female friend on MySpace commented about that. I loved hearing Radiohead and Oasis songs while in a cafe in London.
+ iPod was basically my main companion when I used to do data entry for a few months. Shuffling would shorten the battery. The best I got was about 12h w/o shuffle and 8h with it. Screen brightness had to be at lowest setting. SOT was awful on the 5G. It only improved slightly on the 5.5G.
+ While battery life left alot to be desired, it was my favorite device to use when I had it (Oct 2005-June 2007). Helped that it was alot more compact than carrying around a PSP.
I thought about getting a space gray iPhone SE just to use as an iPod. Closest smartphone to my iPod size but just taller. Last iPhone to offer headphone jack. While iPod wasn't my favorite gadget ever, I had some good times with mine.
