With my iPad only lifestyle, there has been a pain point that’s been present with a lot of iPad Pro users: keyboards.
There never seems to be a perfect keyboard for the iPad that is agreed upon with everyone. In fact there are a number of choices that seem to have some sort of drawback no matter how you look at it.

This is one of my gripes with iOS and why I won’t (yet) go iPad only. If Apple intends the iOS platform to be more than just consumption devices, fixing input – both with the keyboards (physical and soft) and pointing devices (Apple Pencil and introduce trackpad!) would go long way.
For example, when I use a non-Apple Japanese JIS Bluetooth keyboard it defaults to a US QWERTY layout. There is no way to tell iOS what layout is needed when it does the wrong thing.

Be nice with what you write.
