I'm in the market for an IPOD within the next few weeks. I'm going to be doing a lot of traveling for work, 3-4 day trips with a laptop also. I'm leaning towards the mini due to size, scratch resistance, and most importantly the color screen which is due out. I have about a 15 gb music collection which I don't need with me at all times, but I'm wondering how easy is it to transfer music on and off the ipod? Is it as simple as draging and dropping or will it become tedious?
