Graham Lee, on the failings of the iPad:
If the iPad is the Knowledge Navigator, it is not the Dynabook. A
Dynabook is a computer that you can use to solve your problems on, but it’s
also one on which you can create solutions to your own problems.
The promise of the Dynabook is that if you understand what your problem is,
you can model that problem on the Dynabook. You model it with objects-either
your own or ones supplied for you. You can change and create these objects
until they model the problem you have, at which point you can use them to
compute a solution.
Watch this video by Alan Kay on the Dynabook. The future hasn’t caught up
with the past, yet.
