I have the Anki iphone app. Considering the utility and convenience it provides, the price is negligible. For comparison, at a private college, tuition/# of classes ~= $200 / class, so as I use anki for schoolwork, it easily pays for itself.
If you do any sort of utility calculation for products you use, a lot of times convenience will trump price by orders of magnitude. This is one of those cases.
