It could happen. Wil Gomez explains how:
First, Mac Pad would be a touchscreen Mac that runs macOS Bakersfield, or whatever is next on the California meme list. Second, it would not run Intel Inside, but instead be more like an iPad Pro with an Apple designed ARM CPU, let’s call it the A-11 ‘Sizzle’ Series. A 12-inch Retina screen seems reasonable, as would a nominal amount of RAM and limited storage, say 8GB RAM, and 128GB of SSD storage.
I’d buy one.
