I added leopard to my ibookG4 and it is running really slow (dreaded rainbow wheel keeps popping up.) the tech said I have the minimum amount of ram loaded and i need to get more ram. I can order it online for a good deal and there are instructions on how to insert, but i am a little worried about trying to do it myself and wrecking my laptop. Has anyone done this? easy? If i brought my laptop to the Apple store, would they help even though I didn't buy the ram from them? thanks so much!
