> At hi-res, they'll likely not look as correct as the Mac rendering. The higher res you go, the less differences there'll be between the two rendering methods. Fitting to the pixel-grid doesn't alter very much if the pixel grid is small enough. Consider: Rendering a small font size at high-res is equivalent to rendering a larger font size at lower-res. If you look at the larger fonts on TFA's screenshot, e.g. "Node JS Design Patterns 101", there's proportionally much less difference (between Ubuntu and OSX) than at small sizes.
