We won't know what real world performance will be like until it ships, but true to Apple aesthetics and functionality, the first impression of the specs and design of the mMP has exceeded my expectations. An expandable, extreme, beautiful beast. Can't wait to get my hands on it. If you are a Mac professional or just lust for the most powerful Mac ever, this is it. There is a lot of firsts here. Feel free to agree/disagree and why.
