Hello, I just have a quick question. How do eBay sellers sell iMacs with 128MB of ram that ship with Tiger? I thought you needed 256mb of ram to run Tiger. I wanted to get my little niece who is 10 a computer for her birthday and I wanted to know if I buy one of these would it even run? I'm going to upgrade the ram eventually but she just plays games onlines and also uses aim to keep in contact with her friends. I can't believe that; a 10 year old using aim. That makes me feel ancient.
