Hi, I am looking to get myself set up with a Mini system in the next few days and just have a few questions which I would really appreciate some help with: 1. I will be buying 8GB additonal RAM. Is there any point in buying the 4GB Mini over the 2GB given that I'll be replacing the RAM anyway? 2. Will this monitor be ok? http://tinyurl.com/bnuj82h 3. Will I get a free upgrade to Mountain Lion? Thanks in advance for any advice.
