So, after my previous threads http://forums.macrumors.com/showthread.php?t=1456078 http://forums.macrumors.com/showthread.php?t=1462951 I've done a bit of a u-turn and bought a second hand iPod Touch 4gen. My reasoning was a) I looked again at my usage pattern with my iPad, smart phone and regular camera, and realised that what I was mostly interested in was a media player that could play my music, podcasts and Spotify, and b) I found a very good deal on a second hand one and decided to save a big chunk of money that I would have spent on a 5th gen for travel. So far, I'm pretty happy with that decision. My question is, should I update it to iOS6? Will that considerably slow it down/ make it lag?
