Hi all, I have had a 20GB 3G iPod serve me well the past 4 years, but I noticed last month during a road trip that the battery life is down to about 4 hours or so. Here's the dilemma... I want to hold out with the 3G as long as possible (especially given how expensive it was back in the day), but I also hear that the Cirrus audio chip in the new iPod classics are a big step down in audio quality. Apple has refurbished 5.5G video iPods on sale that, according to some sources I've read, have much better audio quality. So this leads to a few questions. 1) for those who have or used to have 3G iPods... how long did yours last... or is it still running? Is a halving of battery life a sign that it's on its way out? Is it too much to expect 5 or 6 years of life out of the hard drive? 2) for those who've had 3G and 5.5G iPods... is there any noticeable audio quality difference that would make it enticing to upgrade?
