For those of you who have the iPad Pro w/ Smart Cover, are you able to use this comfortable on let's say a couch while on your lap? Or does the thing wobble if you try to type? Are there other accessories that work better? I'm considering purchasing the 10.5 IPP for leisure web browsing and light tasks and getting an iMac, or macbook pro w/ EGPU, or building a gaming PC for desktop related tasks. But if the IPP isn't great for lounging and using it on the go, that kind of spoils what I was going for here.
