The iPad Pro starts at $799 (£769, AU$1,229) for the base configuration. If you want to use an iPad Pro more like a traditional laptop, enjoy shelling out up to $199 for the new Smart Keyboard Folio. (There's a smaller, $179 model of the keyboard for the 11-inch iPad Pro.) If you want more storage than the base 64GB, you'll pay. 

If you max out all the specs on the iPad Pro, you're looking at a price tag of $1,899 (£1,869, AU$2,869). With that kind of cash, you could pick up a MacBook Air or MacBook Pro.
