As per title really. I've been trying to read up on it and don't really get it. I'm guessing it's something that replaces the SuperDrive, but then what after that? I'm thinking of what people have been saying about using ab SSD as a boot drive and for Apps, which I like the sound of, then using the HDD for storage. A Kingston 64GB SSD is about £70 and that seems great for what I think I can do, but my main questions are these: 1. What is Optibay? 2. As it removes the SuperDrive, is there a way to still use it? 3. Is this whole process easy for a complete novice? 4. What needs to be bought other than the SSD? Thanks for peoples input in advance.
