I would love a 15 inch iPad. Of all my Apple products, I use and love my iPads the most. I love the versatility of my 12.9 inch iPad Pro (2021/5th generation) which I use for both work and entertainment; for work, with the Magic Keyboard and Apple Pencil, for casual/entertainment use, propped up with the Smart Folio or with a Pillow Pad on the sofa, in bed, etc. In the past I've had both a MacBook Pro and MacBook Air (each at different times) but found that I can do everything I need (personally and professionally) on the iPad. I love that when I'm not working, I can snap the iPad off the Magic Keyboard and use it without a keyboard stuck out in front and wasting space. But what would make my current set up better would be an even bigger iPad Pro. I love having lots of screen real estate--I also always get the largest sized iPhones and Apple Watches. I do also have an iPad Mini, which I use solely as an e-reader.
