Yesterday, I went to the Apple store for a visit and I tried out the new Retina MBP. However, I didn't really liked it and didn't meet my expectations. I decided to go for a 15inch Macbook Pro 2012 Just a few questions: 1) What's the difference between 2.3 and 2.6GHz? Is it much of a difference? I'm thinking of getting the base model, with 8GB of RAM upgraded. 2) Glossy or Anti-Glare? Will one which give me a better resolution quality?
