I have never owned an i or Mac anything but I have to buy a tablet and had decided on an iPad Pro 9.7 - an expensive option!
I have now discovered that there is no official way to have a guest account on iPads - has any iPad user found a work round for this - it is essential that the tablet I buy has this facility
This link is/was for an earlier iPad but is available on my 2017 iPad Pro. How to put your iPad into "Guest User" mode with Guided Access http://www.imore.com/how-use-guided-access-put-your-ipad-or-iphone-guest-user-mode
No the Smart Cover isn't the keyboard. Last year I had the iPad Pro 9.7 with the cover/keyboard and I liked it, but smaller then I'm used to on previous MacBooks.
