I was going by the principle of "If it's [good enough for Google](http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/1.5_r4/android/widget/SimpleAdapter.java#79), it's good enough for us"*  ;)
They also only use the context for making the inflator, so I prefer to leave it like this for portability.
