I have asked my brother to get me one of these whilst he is in the states due to the $ - £ exchange rate being so good at the moment. I pick it up on Thursday

I just wondered if anyone had a 30GB video iPod and what they make of it?
What is the battery life like? Should I need a spare?
I am upgrading from a 5GB ZEN micro MP3 player....I really don't need to do this but boys will have their toys lol
Thanks for any feedback
