I am currently having iPod Nano and iPod Touch. I am about to buy iPad very soon. I have a single computer with me.. I want to ask some of the question related to this. Firstly, do I require separate accounts for each of the devices that I have? How will I be managing this all devices, do I have to perform some initial steps? Will this affect the applications which I own right now? If I sync my ipods and ipad then what will happen?
