I'm probably going to be buying a new MacBook soon, but I have a couple of concerns before I do so. 1. I've purchased some iTunes music on my iMac, and I'm well aware that iTunes uses a protected format. Will there be any way to transfer the songs to my MacBook and still be able to play them? 2. Obviously, 512 MB of RAM isn't going to be enough. I'm considering just ordering it with 1 GB, but if it turns out I can afford it, I may order 2 GB from NewEgg. If I do so, is there a specific brand that will work better? Also, I've heard it's been made quite a bit easier to install RAM into the MacBook; how easy are we talking? Thanks!
