On a 13" notebook display with a 1080p resolution, the RTM version of Win8 scales up some desktop UI elements nicely. However, there are serious issues with Metro, which produces tiles and text that are either too small or too large depending on the PPI setting used. That setting, by the way, is a simple on/off switch that tells the OS to "make everything bigger." Web browsing is particularly problematic, with Internet Explorer 10 introducing ugly rendering artifacts when scaling pages in both Metro and desktop modes. Clearly, there's work to be done on the OS side to properly support higher pixel densities."
