Hi I am still adjusting to the new larger iPad Pro. I purchased it with the ASK. That adds a fair bit of weight, but it also adds functionality. Not sure how much I will use it, as I never used a keyboard with an iPad until now. When I don't need to type on the keyboard, can I remove it and safely use the iPad naked? Do I also need the Smart Cover for those times I don't need the keyboard or is that overkill? If I were to also get the Smart Cover, is there any benefit to the leather one over the cheaper silicone one? I will rarely take the iPad out of the house, so mobility is not a paramount issue.
