I'm planning on buying the iMac that costs $1199 with Leopard in October but I'm not hearing much about it so far. Everyone is either getting the higher end 20" model or the 24" model and not the base model. I want a computer were I can put a lot of digital media on it like music and photos but also do other things simultaneosly (not sure if I spelled that right). Is this computer fast enough do do what I need it for?
