Okay first off, I'm very proud of this heated debate you have produced, and there's some real useful advice in here which will come in handy very soon.
Anticlutch, I am intruiged as to what you mean by "lossless codecs". Explain?
2nd, Thanks for the battery advice and the firmware tip, I'll keep that in mind.
3rd, Dippy, am I right in thinking your link is telling people no matter how you treat/charge your battery, the life will always be the same? Please explain.
4th, DOOM on my iPod?? I must know how to do this!!
5th, I have experienced lag using a friend's iPod Video, but I think that can be classed as "loading times" more than lag itself.
6th, I have used numerous iPods before, from friends etc.. and I've always found the sound quality very much enjoyable, although I think the new earbud headphones are terrible compared to 1st generation ones.
7th. Wile_E, are you saying if I convert my music to AAC it will sound better than mp3?? If so, explain..
8th, Again @ Wile_E, what is this about the iPod's "eq"? I don't understand what you mean here, and the fact you used the word "problem" isn't too comforting. What do you mean by "don't use them" also?
And finally, 9th, what is this rockbox firmware link that you have provided supposed to do?
Thanks for all the replies so far guys, it's been a great help.
