Had my 60GB 5G for a month or so now, taken it to SA and back (12.5hr plane ride each way) and have not encountered any problems with the battery life, i was right in my assumption that the number of times i'll be listening to music for >20hrs straight between charge up points is negligable, if i want to take video with me i have a belkin battery backup pack that takes 4xAA, of which i have 3x2500mAh sets for my digital camera.
+ points:
Music quality - i have music encoded from 112-320kbps and can hear the difference between anything below ~200.
Video - extremely good quality for a small screen (although you need to hold it within an arms length to view it properly)
Looks - who doesn't think an iPod looks cool
Size - 60GB in that little space is amazing, it's more than i have in my laptop
Support - the first one i had tried to melt, email sent to Apple about it on the Tuesday, recieved pre-paid returns package via next day UPS from NL on Wednesday, shipped replacement iPod promptly via next day UPS back to me within a week
Interface - how much functionality can you extract from 5 buttons and a scroll wheel???
- points
Scratches - buy a silicone case BEFORE it arrives, cut half of the protective plastic off the front of the iPod before inserting it so the screen is still covered, no scratches now🙂
Battery life - usually the one thing anyone who doesn't like the iPod shouts about, it's not as good as the competition, but for me it's a non-issue and the fact that a smaller battery is used means that the product is smaller and lighter.
Replacing the battery - again this is something touted by the iPod haters, it was decided that an internal battery would reduce product size and weight, after 3 years or so (at least with my dad's 3G) the battery will not hold it's charge (like any lithium ion battery) and the unit will have to be returned to Apple who will ship a replacement unit to you with a new battery for ~£60 in the UK
All in all i'm more than happy with my desicion to go for the iPod, i played with many mp3 players before coommiting and i've made the right choice for me.
hope that helps🙂
