I also went back and forth on sizes when in the apple store, and visited over the weeks before buying. At the end I just found the 12.9 too big, and well I had a larger laptop at home. And I didn’t want an iPad to replace my laptop... though I doubt it could do that. Overall I’m really enjoying my 11 inch. I find it super comfy and...just easy when curling up on the couch or relaxing in bed. I find myself reaching for it over my larger laptop these days. And I’m having fun using the pencil to journal in randomly...as I would a notepad. Typically I watch shows/media on my tv. But have found the ipads screen is beautiful when watching shows or using the kindle app. I can’t say I’m losing anything since I don’t mind the screen size personally. And am usually curled up with the screen close if I do choose to watch or read something. Basically the compactness of it, and the ease of portability while still giving enjoyment is what won the size over for me.
