May I know is there any good and inexpensive keyboard + case for the iPad? I see many in shopee and Lazada, basically they are differentiated by having or not having backlight, and trackpad. Correct?

Is the pencil useful? I’m not a drawing guy and hardly take notes too…but I’m curious about the usefulness for photo editing, is it finally usable to do lightroom on 12MP photos on the 9th Gen iPad or should I forget about it?
