well i have the 20" iMac (aluminum with camera) for almost a year now. i bought it 2 months before the leopard program came out so mine is the non leopard version

. anyhow, im thinking of upgrading to the 24" iMac with the leopard already in it. so my question is this....
1.) how would i get all my pictures from my old mac to the new one when i get it?
2.) how would i get all my movies and music thats in my iTunes now?
thats all i can think of for now, but im sure i have more questions as the day goes
thanks in advance
