What tasks did you mainly get it for? I have to be honest - every time I read someone say it's genuinely too big for their needs I get excited because that size seems all the better for me to illustrate on with the Apple Pencil. BUT I know very specifically what I'll be using it for. Did you intend to use it as a normal iPad and found that it's too big for what you wanted?
Had no particular plan, but I use my Air 2 for music production, gaming and 'consumption'.
I'm certainly not interested in the art/Pencil side of it, which seems to be the only creative thing that would truly benefit from it.
It's just... massive. And heavy.
