 ### Performance
-The getter is about 3 times as slow as directly using NSUserDefaults, but we're talking about fractions of a millisecond (0.22 ms vs 0.65 ms on an iPod Touch 4th gen). The setter is about 3 times as slow as well (0.20 ms vs 0.61 ms). 
-The numbers vary a bit from device to device and from run to run, but it always seems to be about 1.5 to 3 times as slow. For example on an iPhone 4 the setter takes 0.77 ms vs 0.5 ms when you do it natively.
+Performance is nearly identical to using NSUserDefaults directly. We're talking about a difference of 0.05 milliseconds or less.
