Hey, I'm considering buying an iMac (Which would be my first Mac) soon, and I have a few questions I'd like to have answers to before buying one. I plan buying the new Quad Core 27" iMac, in case it matters when answering my questions. Is it possible/recommended to add non-Apple RAM to the iMac? Are there any disadvantages to this? What are they? Is the new Magic Mouse capable of middle clicking in any way? Is there a wired version of the Magic Mouse? I'm not a big fan on Wireless keyboards and mouses, as they run on batteries. I've read somewhere that to right click in Magic Mouse you have to raise your left click finger, is that true? It may seem like it is according to the video in Apple's website. (The demonstrator raises his finger before he right clicks.) How good are the built-in speakers compared to external ones? In case I have more questions, I'll ask them here. Thanks to anyone helping!
