What do you guys think? Is it worth the upgrade? I could probably sell this one for $600-700. My current is the Apple Cinema 27" with the Mini-Display Port connector. No Lighting port. It's only about 1.5 years old. This is the new one I am considering. http://www.amazon.com/gp/product/B0...pf_rd_t=101&pf_rd_p=1688200382&pf_rd_i=507846 Let me know what you guys think if this is worth it and if you think I can sell mine for that much to pay for it?
