The delivery is outstanding for this price and time. Mr Myasir Khan got a copy that was used on the app store (3 pages of text in a pdf), and some screenshots and managed to string all that together into a very nice product page that is just minor tweaks from a deployment. I'm happy to see how Khan has really put though into placements of texts and images.
