Earlier quoted context omitted.
In English you have to actually press shift to change q to Q. In Persian, this is all done for you. Simply press a letter key and the correct form will appear (automatically changing form based on letters later.) Describing that as "challenging" indicates that the author does not know how to type in Persian.
... He's talking about reading as a challenge. Not typing. It's very clear and unambiguous from the original article.
I'm flagging your comment for claiming I didn't read the article. If the author has trouble reading letters, how can he type well (which was your first point)? Addressing that first would prevent him from using transcriptions and dual sets of flashcards.
