Yay, reddit, you told me that it works on the iphone.  Therefor it will also work on the ipad…maybe not. 

I think I need to limit my scope a bit.  I really should be developing on the platform I plan to use this on…my ipad.  Which means I really only need to know about ipad local storage.  According to Reddit, the persist.js library is a great example, but is also three years old and (and probably buggy.)  I should stick with one browser, one domain.  The less things I have to worry about supporting, the better. 

Right now I am telling cross-browser compatability to go screw itself.
