It's one of the reasons I bought a Kobo e-reader is because they had support for a Dyslexia font (not sure which one it is but looks similar). For me that font helped me in both reading speed and correctness.

I can now enjoy any book while before I would sometimes buy a book but never manage to read it correctly since the font would throw me off.

I can only applaud the initiative but I can get that its not for every person with dyslexia.
