I understand that some folks can use their iPad to replace the need for a laptop, and more power to them. Especially, if they have a nice desktop computer waiting in their workspace. I prefer to use the iPad purely as a tablet. Great for content consumption and reading. Also, useful as a secondary screen with Universal Control.
It has been my experience that adding accessories tends to get in the way of the simplicity of the iPad. When I use a keyboard case, it just feels like a poor substitute for my MBA. Even when I use the pencil, it feels awkward because I hate writing on the glass screen. But, when I strip all of that away and just use the iPad as a touch first tablet with a light case, everything just feels so natural and easy.
If I want a laptop experience, I will use a Macbook. If I want a tablet experience, I’ll use an iPad. If I am leaving the house and not sure what I might need, I default to the MBA……then, I know that I will be covered.
