I found that the stock setting of 240 DPI made everything a little too large for my preferences. I tried 180 DPI first and that made everything a little bit too small. At 200 DPI everything seems just right, except that the stock launcher does not take advantage of the additional area. I installed the Google Now Launcher and that does make use of the additional area, and other launchers such as Nova likely do as well. I haven't installed anything other than the launcher from the Play Store yet, so I don't know if this will give me any issues with installing apps, but I know there are fixes available for this. Also, it is obviously very easy to change DPI by editing build.prop if you have root access, but there is also a method posted in the forums on how to change it without root.
