You just ordered one now?! They may already be sold out, but if not, congrats!

Take Tony's advice and read the FAQ. It will help. And don't get too overwhelmed by all the organizing you need to do. Think of it as something to do while you are waiting for your Rio to arrive. That is what I did. I had to wait weeks for mine to ship from the UK and I was fine with the wait because spending the whole time updating ID3 tags and ripping more CD's was almost theropy!
