Perhaps, but nobody wants to carry around (and charge, and sync) two devices when they could carry around just one.

If I had a device that worked like a MacBook and an iPad, so I could use it like a laptop at a cafe and like a pad on the train, that would be a pretty damn neat device to have. And eventually, I probably will.

Something like this: http://aidacase.com/keycase-folio-deluxe-with-built-in-keybo... might work for you eventually, though it may seem silly. I think the difference in this is that you can just open the front flap for quick, instant-on tablet access, and unfold it further for keyboard usage vs. having to set up / maintain two different systems or use a tilt/swivel joint to access the touchscreen.

Something like that would be good, yes. Though obviously MacOS-based and not iPad-based, cuz I need my Terminal.app et cetera.

The syncing problem should go away once all of our files will move to the cloud.
