"I’d accidentally create the hybrid Apple computer of my dreams."
And of other people's nightmares. A macbook and an ipad frankensteined together into an actual laptop?
Sorry, it's a good hack and all, but definitely not for me.
An ipad that's actually internally a macbook, running the full unix-like system, to which you can attach a keyboard of your choice, is more likely what people have in mind as the solution here. use it like an ipad when you just want to read, then stick it on the keyboard dock to do work. Actually let's make it an ipad that's actually a thinkpad or framework; something less coercive than apple or microsoft.
