Hi there, Recently, my roommate (Windows XP user) and I (Mac fanboy) were having the good 'ol PC versus Mac debate. I told him I'm planning on upgrading my PowerBooks RAM to 1,25 GB, and said it will probably give me a real perfomance boost. He says that RAM upgrades on Windows usually aren't that noticable (I agree, I've previously doubled the RAM of my old laptop, and it didn't speed it up too much). So my question is this, why does OSX love RAM so much more than Windows does? Or I am just imagining things?
