The "iPad" is being talked about as the budget iPad on here while the iPad Pro is "pro" and priced as such. Is the "base" iPad no more? Will the iOS 11 features work well on iPads that are non-Pro (which are the vast majority of iPads in use)
Apple has made it pretty clear with their new lineup. If you want Apple Pencil or Keyboard, buy Pro. If you don't want it, buy iPad (2017). It's a really simple choice between three products.
