Hi Sandy,

Apple has a new iPad Pro specifically designed to turn an iPad into a laptop. It is especially expensive, starts at $799. https://www.apple.com/ipad-pro/

For something more wallet-friendly, the new iPad with a larger 10.2‑inch Retina display and support for the full-size Smart Keyboard starts at $329. https://www.apple.com/ipad-10.2/ I think this is a good bet for you!
