I absolutely abhor 16:9 on laptops, one of the reasons why I'm using a macbook air is for the excellent 16:10 screen. If you go shopping for ordinary PC laptops in the $1000-1300 (USD) price range at a place like Best Buy and take a look at the quality of the LCDs, it's amazing how many absolutely shit 16:9 1920x1080 displays are being sold on machines at the same price as the macbook air's higher-dpi retina display.
16:9 on a desktop seems to be unavoidable these days, and indeed there's the whole popular trend of ultrawide/ultrawide-and-curved monitors now which go way beyond that.
