Well the screen Quality isn't that bad actually, however i did notice the whites are a little blueish and slightly off white compared to my previous 15" unibody, and my 13" Air, which for some reason has amazing colours and produces milky whites. Im not doing any professional work at the moment, however I do photography as a hobby and currently in the process of building a Portfolio Webpage. Often i do my editing on an External Dell Ultra-sharp IPS display(which has very nice colours) I do plan on purchasing the Spyder4 in the near future, but for the meantime just wanted to try out a few calibrated presets and compare them with mine to see which results i prefer.
