That’s a very niche use case and gonna be a very expensive recipes look up. Also I’m not sure the desktop mode of a website actually look better on a Duo because the text and links would be quite small to navigate with a finger and most probably it would by default get the website optimised for iPad/tablet view.

As for the bigger keyboard, I have tried that in iPad mini. It’s horrible. Because the distance between the keys is too far in that case and it actually slows down your typing. I can imagine the same in Duo when you use one half of it as the full keyboard
