Apple iOS Never to Support Leica DNG?

In an interesting piece about "Why Photosmith dumped iOS's built-in raw-photo support" we learn that the developers of the Lightroom companion app for iPad opted to build in their own raw-photo support to get better control, avoid Apple bugs, and support more cameras... Such as Leica, among others. Apparently, Apple's API and camera support are lacking; difficult to work with and buggy as well. If you're shooting a Leica, check out Photosmith!

Then you get to practical stuff like the fact that they don't support Leica DNG images and probably never will...
