Just today i received my package from tech-com shanghai via DHL. people say that the 15 is too heavy, But its as light as my '10 dell xps. Ill be using this for architectural renderings and ill be bringing this everywhere. I got the AG antiglare and its extremely good, its sharp and has good size realestate. A have seen the retina in real life, although its much smoother, i see no reason for me to get the retina anyways, this screen is gorgeos! As for renderings, i have yet to open larger projects but as for now, with the 2.6ghz and 8gb ram, its running ever so smooth. I would like to thank everyone who helped me with my decision. Im greatful that i could own such a beautiful and powerful machine.
