I think I made my mobile working recently. The Bluetooth keyboard + iPhone 6 Plus is very powful tools to work outside.
I suppose we do not use the laptop after 5 years around 2020. The specification of the mobile should be reaching to the current laptop. Then, we do perform the same work on iPhone instead of MacBook Pro.
And we are able to make the space for the mobile industry. What is the necessary tool in much more smaller size? It would be the pencil style phone or something like that.
Those futures will come soon…
