I'm debating getting an ipod. I'm aware of all the bells & whistles, I just need some advice about batteries. And I know how techy these forums can get, so keep it simple please guys. OK. What is the availability on replacement batteries for the current gens of ipod regular & mini? can you provide uk prices? Are these details still going to apply when my ipod runs down for good, or am I better buying one when I buy the unit.... Ta.
